I hâted the author's unnecessary nerfs, the mc's leaving every fight wounded or half dead, the mc's trying to strengthen his loved ones but not improving himself and complaining in every battle 'my body is too weak, I can't use this skill, if I were at this level I could use that skill.'. I put up with it while the personalities in his other life were just in his head and just commenting. But when those personalities in his head suppressed the mc and started doing things according to their own minds, all my desire to read went away. After Cursed gamer, I said I would never read this author's novels again, but I succumbed to my curiosity again. Overpowered tag is a lie.. What a waste of time..

I've watched hundreds of knife making videos on youtube. It never gets boring.

Who cares.. All these mc's, their targets start out as Grayfia-Rias-Akeno and then they get stuck on these aika-type side missions. I bet you'll join the kendo club in future episodes and develop the side characters in kendo too. I remember that human magic in dxd is done with calculations. Your parents are billionaires, tell them about the supernatural side. Ask them to research a magic book. Try to learn senjutsu. Do meditation, maybe the system will help you learn it.
