I only know standard manga/manhwa/manhua x3 I've never watched Kirby or Mario stuff so I just guessed from what ppl said from the games, oopsies didn't know they had their own thingie. I'll fix it for ya :3

Here they are in order :3

Re:Monster - this is a guess, I haven't read it in like 2/3 years.

That Time I Got Reincarnated as a Slime

BOFURI: I Don't Want to Get Hurt, so I'll Max Out My Defense

Arifureta: From Commonplace to World's Strongest

Kirby

Attack on Titan

Finally the spider: So I’m a Spider, So What?

Some similar ones too, just in case you're looking for this genre:

I Grow Stronger by Eating

Berserk of Gluttony

I was curious about this as I read a few BL Manhua. It was pretty well accepted since at least the Han dynasty, and has been argued that westernisation during the Qing dynasty is what introduced the opposition towards it. I mainly just read about it on this Wikipedia page so I could also be completely wrong ^ - ^ `

A singing saw, love the ghosty sound of it.

Sounds like a great idea, I'm sure that'll be a top quality learning experience for the poor who are already facing a cost of living crisis, that'll really teach them...
