An idea for the MC to make money or just perform at a talent show would be to do a music video of the song “Necromancin Dancin” using his undead as back up dancers/singers when they can speak. I think it would be funny and irritate Sona so a win-win.
Kuro should get an undead pale horse and ride it to the school claiming to be death just to irritate Sona. I’d take every chance I get to irritate her.
I liked the story, , , the only thing I didn't like or understand was why even he updated the physique only increased to an adult man? like he's going to be physically weak until when?
