Ah, I found it, it's Hakkenden manga. I just remembered it was from the same author as Komatta Toki ni Wa Hoshi ni Kike so I found it easily!!(๑•ㅂ•)و✧
It's also an anime if you're curious.
There is about 2 seasons out right now.
After I read the manga I was reaaallly frustrated that there wasn't any new chapters so I read the comments and saw that there was an anime also. (so it may have happened that I watched the whole anime in 2-3 days) I was so happy to finally know what happened!!!! ヾ(☆▽☆)
Chapter 4 page 34, What's the name of that manga??? I've read a part of it before but I can't remember the name and I want to read it again!!!!!!
