Turning back time a bit, Kisuke's Reiatsu was largely ineffective against the girls aside from making them a bit sluggish at the start until they could acclimate themselves.
Even though Kisuke couldn't attack back, the girls still did their best to control his movements before going in for a strike to ensure a good hit. While this is a good practice, it should show how much experience they were lacking since a real battle isn't just a simple game where you could win through a series of planned actions. Sometimes, it's better to just dive into the danger to change the pace and take control of the momentum.
Surprisingly, Claire, Kunou, and Tanis managed to realize this when Kisuke suddenly started to effortlessly dodge and block their attacks while also predicting where and when their restrictions on him would appear and sometimes, even return them to them.
At this point, Kisuke had already 'killed' them more than 5 times. Though it might be less than that since they were able to back out a few times, but not always in time. And Kisuke doesn't really know what sort of healing capabilities they had, but he assumes that they'd never forgo practicing such techniques and spells.
Those who knew Kisuke might think that he's holding back, but to a certain extent, he's actually not. The reason he was only able to 'kill' them more than 5 times was because of Claire and her [Worthless].
Because of Claire, Kisuke's stalwart defense became a cardboard box so he was actually in danger of being severely injured. At this point, Kisuke had actually become afraid that Claire could also disable his High-Speed Regeneration so he released his Hollow Form in an attempt to increase his resistance against her [Worthless].
However, Kisuke could only laugh. Even though his resistance really went up, Claire only responded with finer control, and the moment an attack was about to land, the white Hollow matter that was covering his skin would melt away. Not just Hierro but also his Cero, Bala, and even Negación which he hadn't used much were disabled.
Next, Kisuke released Benihime but the same as with his Hollow Techniques, all of Benihime's energy-based techniques were also dispersed as soon as they appeared. Thankfully, his Flash Step and Shunko were still working with the latter having the same fate as Hierro, albeit, a lot tougher and slower to melt. But when he saw Claire's eyes curiously eyeing everything he was doing, it made him nervous that even his mobility would be reduced.
Another set of techniques that Claire's [Worthless] didn't work on fully was his Kidou spells. But after seeing them enough times she should also be able to disable the weaker spells without any problems.
Because of all of this, Kisuke had a certain thought, 'Should I bring her to that world? She'd be one of my greatest weapons, but I might get killed by her parents.'
Although Kisuke's attention was mostly on Claire, Kunou and Tanis' abilities couldn't be discounted. Unlike Claire, who's an allrounder, Kunou and Tanis had fallen into a specific role and trained for that role. Kunou, with the versatility of her Youjutsu, became the battlefield controller, creating opportunities for her allies and limiting her opponents.
Tanis, on the other hand, tapped into her Dragon lineage and used her naturally strong physical attribute to become the main bruiser. Using both Draconic Aura and Ki, her fighting style came to resemble that of Crom Cruach. In other words a complete musclehead.
About an hour after they started, Kisuke was finally able to figure out what their limits were and was about to wrap it up by telling them to give him their best shot. And they delivered way more than Kisuke had expected.
The first one to move was Tanis gathering and fusing her Draconic Aura and Ki on top of her palms, creating a purple energy ball the size of a basketball court. Meanwhile, Kunou kept to her role and tried to tie Kisuke in place while also obscuring his senses by creating a thick fog that covered the three of them.
'Although it obscured their presence, it doesn't make sense to use it on Tanis since that enormous thing can't be hidden.' Thought Kisuke, 'It's so obvious that Tanis' attack is also just a distraction. So Claire is going to sneak up on me?'
Kisuke was correct, albeit, only partially.
Within the thick fog that confused the senses, a big purple ball of energy blasted through and came crashing down on Kisuke. Since it was big, it was also slow so Kisuke had enough time to try out a few things.
Kisuke first cast Danku (Splitting Void), but he'd already used it several times in front of Claire and understandably, the barrier disappeared into thin air. Next, he brought out his Millon Escudo (Million Shield), but before it could expand, it disappeared and Kisuke felt it return to the back of his head where it remained inactive.
He already knew what was going to happen if he just received the energy ball with his body so he raised Benihime over his head with his left arm to slash through the ball.
Kisuke could have dodged, but within this limited space of the training ground, he'd have only left himself open if Tanis could control the ball's trajectory.
At the moment of contact, there was a large shockwave that cleared the rubble and leveled the surrounding stones. Benihime sank into the energy ball but was stopped by the incredible force behind it. However, Kisuke noticed that something wasn't right, 'This energy ball... Doesn't have a core?'
He couldn't think much about it since he knew that Claire would be coming any second now and he only has his right arm to intercept her.
Kisuke expanded his senses within his perimeter, but after looking around, he still couldn't find Claire and he was already about to cut the energy ball in half, 'Did she miss the timing?' But thinking about the teamwork they'd shown until now, that's most certainly impossible.
At that point, Kisuke suddenly felt something weird. Something that shouldn't be here.
He immediately expanded his senses further but because of the energy ball in front and the fog around him, he took some time before he could make out what was behind the attack. Then it happened. A bright golden arrow of light pierced through the ball of energy and reached Kisuke in an instant.
Kisuke was shocked at this incredibly out-of-place Power of Light that only the servants of the God of the Bible could use, but he had to move. He wanted to block it with his sword, but Benihime was still stuck within the remnants of the energy ball. Without much choice, Kisuke raised his right hand to catch it.
Before he could touch it, the Hollowfication of his arm was undone. Nevertheless, he was already expecting such a thing to happen and gritted his teeth as the arrow of light instantly burned his hand and started to work its way up his arm.
After securing it within his palm, Kisuke took a deep breath and spontaneously released his strength to flick the arrow away.
The deflected arrow continued traveling and eventually reached the wall of the training ground before exploding into a pillar of condensed power that could instantly vaporize those High-Class and below.
Kisuke didn't look back at the destruction and made sure that there were no more incoming attacks next.
The 'empty' energy ball evaporated and the fog dissipated, revealing the three girls huddled together and catching their breath. In Cleria's left hand, Kisuke could see the remnant of a bow made out of light, "Now that's what I would call a Balance Breaker. What the heck? Did she somehow inherit Uncle Masaomi's exorcist power? How is that even possible considering how she's fully capable of using [Worthless]? Isn't that cheating? Did another cheat character just make her entrance?", Kisuke muttered to himself.

28th00: Ouchie. If only Kisuke got to keep his Worthless, he’d be unstoppable.
Goyya: He’s too OP if I still give that to him. It’s the reason why I had the Hougyoku consume his Devil Part and returned it in another form.
While his arm was slowly healing, Kisuke approached the girls and asked Claire, "How did you do that?"
Even though she was very tired and laying on the ground, Claire gave him a cheeky smile and proudly answered, "Amazing, right? [Worthless] really is wonderful."
The moment Kisuke heard that it suddenly clicked in his head, "...You used [Worthless] to forcefully tame both Demonic Power and Holy Power?" But even after saying it out loud, Kisuke still couldn't believe it.
"It somehow worked." Claire shrugged her shoulders, "But it took a while to smooth it out."
Kisuke was rendered speechless because he knew that was impossible to achieve with just 'It somehow worked.' Naturally, there are cases where Demonic Power and Light Power could mix and the most popular example of this was Yuuto Kiba with his Balance Breaker. However, there's a big difference in how Claire acquired her equilibrium compared to the former and that was that she's directly storing both Powers inside her body.
In Yuuto's case, he could use Light Power with the help of his Holy Swords and that's the same for those who could use both Demonic Power and Light Power. They needed a medium to facilitate their use like a Sacred Gear or some other special tool that was related to Heaven. Even then, when used, it was always a mix of both Powers and their opposition was its main point to produce a huge amount of force.
As only Devils with a strong relation with Heaven could use something like this, there aren't a lot of people who could do it.
In Claire's case, with the arrow of light that she used, she's fully capable of using both Powers in their purest form on top of not needing a medium to achieve an equilibrium, 'If her [Worthless] could really do something like that, then her ability was already bordering that of a Super Devil if she's still not one. That would explain how she could easily neutralize my Shinigami and Hollow abilities.'
Asking any further questions would be useless since she probably isn't really fully aware of how ridiculous her abilities are. Instead, Kisuke congratulated the girls, "Good work. From the spar just now, I'm sure that the three of you are all on Ultimate-Class level, and with your Soul Gears, you should be able to match an average combat God and if you are together, you are fully capable of matching a Leader-Class God."
The three of them weren't aware of their real level and thought they were just around High-Class due to the absence of competition. But after Kisuke's confirmation, all of them stood up and cheered up despite their heavy bodies.
'That's still a bit of an understatement but this should be enough to make them careful on how they swing their fists around.'
However, their celebration was cut short by Kisuke's next words, "And now that we're done, begin cleaning up and restoring this place, at least to how it looked before we started."
The girls were stunned and looked around the training grounds that were utterly trashed beyond recognition before turning back to Kisuke, "...All of this?"
Kisuke nodded while returning back to his Human form since his arm was now feeling a little bit better, "All of it."
The girls looked at each other and knew that this would be a daunting task in addition to being a massive pain in the ass. It was then that Claire noticed something and asked, "...Why do you sound like you're not helping?"
Before answering, Kisuke pointed in a certain direction. The girls followed his finger and saw Ophis and Lilith silently standing at the edge of the training grounds. Since they'd been with her all these years, they could tell the mood they were in despite not showing any apparent expression, and right now, they could see a 'lonely' aura on the two of them. Was it because they felt they were being left behind?
"I have the most important task. Pampering and consoling those two."
The girls didn't even question Kisuke's declaration and nodded with all their might, "Understood. We'll do our best."
.

Three hours in, the girls are still working hard to restore the training grounds. Meanwhile, Kisuke was feeding Ophis and Lilith various things throughout those three hours. Since they aren't exactly normal, the food that they are taking was just being absorbed by a bottomless pit.
Kisuke, Ophis, and Lilith were just talking about random things that were focused on their daily lives and how they were adjusting to Human society. They immediately admitted that it was confusing and hard. They also had poor memories regarding common sense and manners but Kisuke attributed that to them not really understanding the underlying meaning behind 'common sense and manners' since they didn't really need it until now.
"But it seems that you two aren't a bit frustrated. Are you enjoying it?"
Ophis and Lilith immediately nodded without a shred of hesitation and the former said, "I desired peace and quiet. That hasn't changed, but the meaning of it did... The previous peace and quiet I was hoping for was an eternal silence, but right now..."
Ophis tried to find the right words but couldn't so Lilith continued for her, "We desire peace and quiet... And the fulfillment it brings instead of the emptiness."
Kisuke understood what they meant, "That's great. I'm glad that you were able to find something fulfilling."
Ophis nodded, "And it's thanks to you. I'm not sure what I would have become if you didn't reach out to me."
Kisuke turned to her and smiled wryly, "You know why I reached out to you at that time. Don't make it sound like I lent a hand to save you."
Ophis nodded again, "That isn't important."
Lilith then pulled his sleeve to get his attention, "As a show of gratitude, we'd like to help you."
Kisuke patted her head and chuckled, "You've already done a lot for me."
Ophis grabbed his other hand and put it on her head herself, "But you're currently lost."
Kisuke was surprised for a moment before sighing, "...Amazing. You two really have eyes for the most inconvenient things."
Ophis and Lilith kept staring at him as if trying to pressure him to speak and it didn't even take a minute for Kisuke to cave in, "I want to bring Claire to a very important place because she has the ability to help me immensely. However, that place is also very dangerous and my priority should be your girls' safety."
Ophis then let out a small snort and returned her attention to the snack, "Unnecessary. We can protect them. We're strong. And I can protect you too."
Lilith also did the same as if losing her interest at his 'insignificant' worry, "We're coming too if they're going. There's no question about it."
Kisuke didn't say anything else and just contemplated on what he should do, 'If it was the past me, I wouldn't have hesitated like this. After all, apologizing is a lot easier than getting permission.'
