Chapter 18: Chapter 16: kill 1
3rd POV
MC: "So, what do you want my help with?"
MC: "I want to save a friend of mine but ... I'm too weak"
MC: "Alright. I'll help you. You owe me a life"
POV Rihan
So what I think is right. He wants to ask me to save Asia. But it's strange if I remember correctly. Rias and her peegare will help Issei. Perhaps my appearance yesterday has changed some things.
Right now, Issei and some other Youkai are heading towards the church. I decided to let some of the most capable youkai follow. I want them to have experience fighting with other factions. They are all in their human form. It is not difficult to do this. They just need to wear an illusion. What all youkai have the ability to do. Including Tomita, Sasami, and Shinobu.
Issei: "Rihan-san, are you the leader of the youkai in the house?"
MC: "That's right. If I remember correctly, I have more than 1,000 Youkai under me"
Issei: "What? Like a legendary Hyakki yakou?"
MC: "Yes, but most of them are outside to protect the territory" Muzan has left more than 200 Youkai in the 'Main House' An old mansion behind the hill. It's on the outskirts of Kouh. They are there to be ready to fight with me. Currently, in the house I am in. There are about 100 Youkai.
3rd POV
Issei was silent to digest these words. The person he wanted to punch yesterday was the leader of a monster group of over 1,000 members. Even the 3 Youkai accompanying him gave off a strong aura. That is the result of the practice. These 3 people awakened the <Busoshoku Haki> at a basic level. Enough to help increase their attack and defense power. Especially Sasami, who absorbed the blood of Rihan.
MC: "Oi Issei. You still haven't explained to me why Rias is not helping you."
Issei: "After yesterday. Buchou and I got into a little quarrel. That's probably why she didn't want to help me." The words of yesterday's Rihan had an impact on Issei.
(MC: So did my appearance yesterday make him change a bit? Perhaps the fact that I said that Rias is using him?)
.....
After a bit of time, the 5 of them approached the church.
MC: "We will enter from the front door. They are just weak fallen angels. No need to worry."
POV Rihan
Entering the church without any difficulty. I could see the pipeman standing in front of me. He was a white-haired man with a priestly outfit. Priests 'Freed Sellzen'
Freed: "Yo, nice to see you again"
Issei: "The priest bastard" Issei shouted angrily.
Freed: "I used to have a record of never letting a devil escape from my palm. But thanks to you, I've ruined it, are you happy?"
What's up with this crazy guy?
Freed: "All because of your demons, you should die ..." screaming like a child who lost a toy.
MC: "Oi. Can you shut up?" I said while picking my ears.
Freed now noticed my presence. I purposely reduced my presence to see what this bastard was up to. But he said such silly things that I couldn't stand it anymore.
Freed: "Oh, who are you. Another devil?"
As soon as he finished his sentence. I rushed towards him with the fastest speed while in human form. This made Issei think that I was teleported and the 3 Youkai were surprised by the speed while in my human form. I swung the sword towards the priest's neck. Cutting off his head made blood splash everywhere. A typical death of low-level villains.
MC: "I told you to shut up."
The fact that the priest was decapitated so quickly made Issei shiver. Perhaps this scene was far too brutal for him.
MC: "Oi, let's go"
