MTL - I, The New Hokage of Konoha - Chapter 371 final battle

An ordinary (?) grandfather, Choi Chuntaek. In an effort to protect his granddaughter, he started the virtual reality game 'Arkstar.'

Then... he accidentally obtained a legendary class?

«Bleh.» — Imp. An Imp, a monster known to kill with a grin, a demon of the world, a creature of incredible might! Something that no force in the world can stand against! At least that’s what the Main Character would like himself to be, the reality is very different, however.

Exactly that Imp stumbles along a path of unfortunate fortunes and grows through it, in a world that hates its very existence.

It grows more intelligent, more powerful, simply better at whatever it needs to do. Amongst other things, that includes raising children, killing Soldiers, and carving wooden figurines for money.

The person whom the world revolves around.
