sakamoto days, tougen anki, chainsaw man and blue flag

thank you very much

One Piece
Claymore
Fullmetal Alchemist
(I've read the 3 above so many times the pages are falling off)
Ares - The Vagrant Soldier (this one's a manhwa - the pages aren't falling off because I've bought the collector and I read it online because I'm scared I'll damage them)
Berserk (the pages aren't falling off yet because I never open them at more than 60°)
Alive - The final Evolution (You will cry)
Fruits Basket (it's still good even though it's old)
Houseki no Kuni (You will CRY)
Dogs: Bullets & Carnage (watch out, that one seems to be discontinued)
My Hero Academia (people seem to dislike the latest chapters but I'm still enjoying it a lot)
