(A Few Days Later)
Shit, class is so boring, why haven't I dropped out yet?
But the moment I look out the window, I saw Issei running away from a group of girls along with his best friends and I finally remember why.
But I do have some theories now on why a picture of issei was inside the Occult Research Club's room, either he has great potential which is unlikely, or… he has a sacred gear.
And boy oh boy, if he does have one, well that would be unfortunate for him because…
"You would become my experimental subject," I said with a grin as I watch them goof around in the distance and I'm still waiting for the perfect opportunity to come up.
(A Few Hours Later)
"Oh ho?" I muttered as I saw something interesting on top of the rooftop I usually stay at, there in the distance, I saw Issei talking to a girl with black hair and big boobs, big boobs have been more common than I thought huh.
But from their interaction alone, I instantly knew what was going on.
"A confession? Oh the sweet joys of life, if only it was actually special when you know there is an infinite amount of Issei, an infinite amount of me, and more. But at least someone saw Issei as charismatic and likable, but I'm pretty sure she has ulterior motives," I muttered while shaking my head and continuing to eat my sandwich while my hair fluttered with the wind.
With the sandwich now eaten, I went to snap my finger and mana soon came rushing in towards my body because guess who found a way to forcefully make mana go towards a certain point and in turn increase my mana absorption, it's this guy.
It was actually pretty simple, just think of it as a magical magnet made with magical objects like a mana crystal.
With me sitting down in a lotus position, I slowly started to form my second magic circle in my chest which has been a long time coming because the levels between Tiers are so vast.
A Tier 1 magician can't hope to beat a Tier 2 magician without the help of luck as a Tier 2 has a stronger body, more mana, greater mind, and more but the spells of this Tier were still child's play compared to the Interdimensional Transport formula.
And after a while, an explosion of mana erupted from the formation of my second circle as I let out air that I was keeping in for a long time forming that second circle.
Well, now that's done, I stood up and appeared inside a certain room filled with random gadgets strewn about because I finally made my own lab hidden somewhere, though the resizing technology is already within arms reach and I should achieve it in a few days so a portable lab is near.
With a snap, a hole appeared in front of the white wall in front of me to show a target dummy I can hit and without hesitation, a red magic circle appeared in the palm of my hands, and out came a pillar of searing hot flames.
"200 degrees Celsius, that's pretty decent considering it's a long stream of hot flames that continuously shoots out," I muttered while another dummy came out of the wall as I continued to test out my spells on the dummy, even my physical strength in human form.
Even my armor form has more than quadrupled in strength compared to the time I was Tier 0.
"Finally finished, the data shows that a Tier 2 magician is about 2 times more powerful in all areas of magic from versatility, mana usage in respect to mana amount, etc. Well, that's finally done," I muttered and appeared back on the rooftop where, unluckily enough, a girl with brown hair and brown eyes was coincidentally eating at.
"…" the girl just sat there holding her sandwich without uttering a single word as I pointed my hands at her and before she could respond, she was knocked unconscious while her previous memory was erased.
"Magic am I right? Pretty convenient without me having to bring around my memory eraser gun," I said while leaving the rooftop to go back to my classroom.
(The Next Day)
"Oh the sweet Saturday, a great time to go on a date," I said while glancing at the two in the distance while I was chewing on some dango I bought in the store just beside me.
I know you're scheming something you lying bitch, Issei is so disappointing he probably would have been arrested if not for the interferences of the devils of Kuoh Academy, good thing I've already concealed my mana from them so they won't know I'm a magician.
But what for?
Maybe to seduce Issei?
So she probably knows something about Issei, though I do wonder what it is, probably a Sacred Gear.
(A Few Hours Later)
"Oh I fucking knew it, she wasn't human," I muttered while hiding behind a bush and munching on more dango because why not, it's like watching a mildly interesting drama.
"Blame God for implanting a Sacred Gear in your body," said Raynare as issei lay there on the ground with trembling eyes while blood spewed out of his stomach, and just like that, he fell down to the ground dead.
Welp, it's action time!
"BANG MOTHERFUCKER!" I shouted out of the bush while shooting a beam of red light from a laser gun on my hand that accurately hit the fallen angel's stomach which made her eyes widen.
"W- what?" said the fallen angel with wide eyes as she grasp her stomach in disbelief and from the searing pain she was experiencing right now.
"Badabam!" I shouted while three more laser beams shot out of my gun and just like that, the threat was neutralized by death.
Then with casual steps, I crouch down beside Issei who was actually still alive and was just on the brink of death so yay for me.
"Sup Issei, mind drinking this potion for me?" I said while opening his mouth and pouring red liquid inside it and miraculously, all of his wounds and internal bleeding stopped while he was knocked out unconscious.
"Mission done, I can't believe a Sacred Gear and a Fallen Angel fell down to my lap just like that," I muttered while I grabbed the both of them and appeared back inside my lap to start my desired experiments.
First, with this fallen angel, it's time to use the wonders of biology!
A pod soon appeared on the ground beside me which I dumped the Fallen Angel inside, and soon, data flashed by the screen to show how the biology of Fallen Angel functions and…
"It's… less cool than I thought. It's basically the same as humans but just more powerful physically and has attunement with Holy Power, well holy shit, that's lame as fuck compared to a Horned Dung Beetle that can grant 1141 strength multiplier relative to the body weight. Oh well, making a Light Weapon still sounds pretty cool, besides, I can just revert back my race later," I said while shaking my head in disappointment and went to press a button on the control panel beside me, and out came Holy Power from her body along with a certain gooey liquid.
Basically, magic is dumb in face of science, I don't need to go become an angel and then fall down to become a fallen angel, no, I just literally get their DNA, and bam, a potion I can drink to turn into a fallen angel, magic isn't that complicated when it comes with race.
"Well, bottoms up," I said and chug down the liquid that fell down to a glass tube, and just like last time, I kneeled down on the ground in pain as more tubes went to connect to my body that poured in tons of Holy Power into my system.
And soon enough, a pair of black wings sprouted from my back along with my hair becoming darker than usual but all in all, the process was finished just like that.
"So… this is the power of a Fallen Angel?" I said while a light blade appeared in the palm of my hands which I swung around with raised eyebrows.
"And I can even fly without flapping my winds, magic am I right?" I said with a joking tone as I tried to cast a magic spell base on instincts and out came a radically different magic circle from the one I was used to.
It was colored golden yellow with themes of holiness and angels from the symbolism it holds like gracious wings that form the edge of the circle.
With Holy Power coursing through my body, I charged up the magic circle to produce a simple effect.
To make the dummy in the distance harder and more durable and it fucking did which just blows my mind because… it's just literally Demonic Power but more holy.
Yes, they are essentially the same thing but just weak to each other.
Well not really, Holy Power is connected to faith, religion, etc. while Demonic Power is just "imagination go brr" but they essentially produce the same effect, any effect really with enough energy used.
"So it was cooler than I thought, but eh, I can still replicate that with science and now I'm also weak to Demonic and Holy Power so yay, but flight is nice though," I said while I felt my magic circles inside my body still there, probably because I didn't get reincarnated as an angel and was still a human previously.
Wait… can I use Holy Power to power up my human magic?
Only one way to find out.
"Fireball!" I shouted as out came a golden red magic circle with a different design still holding themes of angels and faith but the effect was more magical because the fireball that shot out was made out of Holy Power!
"Holy shit, is mana and Holy Power connected?" I muttered with wide eyes as I quickly went to insert my hands through two tubes that sprouted out of the ground and spew out mana and Holy Power into the two because this just brought a new prospect for me!
With a quick dash, I went towards the master computer of my lab and saw the data it presented…
"Holy shit, I am able to transform Holy Power into mana! But… how do I transform mana into Holy Power?" I muttered while quickly listing down the properties of Holy Power…
"Holy! It's Holy!" I shouted as a moment of revelation finally came upon me and I finally knew how to do it.
With a quick snap, a holy cross shot out of the ground which I grabbed and I inspected it with scrutinizing eyes trying to understand the secret it holds.
"Magic circle… magic circle! Okay… this should work if my theory is correct," I said as I sat closed my eyes and focused on the magic circles inside my body, and slowly change the design to vaguely matched the Fallen Angel Magic Circle, as I did that, I felt my mana slowly accommodating to the change and out came Holy Power!
I can now convert mana to Holy Power and vice versa!
This means… mana is the equivalent of water!
But this is only once, I still don't know if Demonic Power would act the same but this is still insignificant to the true prize of today.
"Groan, it's finally time to see the secret of Sacred Gears," I muttered while standing up and walking towards a certain tube holding the naked Issei floating inside a green gooey liquid that is essentially keeping him alive inside that tube.
"Oh Sacred Gears, a creation of God to bestow miracles on Earth, I wonder what secret you hold and how do I gain one for myself, besides you know, transferring my consciousness to Issei's body which is another whole can of worms to deal with," I muttered while pressing on a certain button on Issei's tube.
AN: This is 2040 words, you're welcome.
So I was mentally drained nearing the end but basically, what he meant by mana being water is that water is a universal solvent and my mind somehow connected that to mana being able to transform into Holy Power which is just purely illogical, it should have been something like energy but oh well, what's done is done and I don't want to rewrite.
The Sword of Damocles hangs above each and everyone one of you with its ever present threat of despair, so send me some power stones with your power of friendship and save the thousands perhaps even millions to come who will read this masterpiece immortalized in the tunnels of time.
