I'm Yakuzen Kusuri! I like creating whacky drugs since I come from a family of pharmacists and chemists, yep yep! I like ending most of my sentences with "yep yep"; it's a little quirk I have for no particular reason. I'm also a 3rd year at Ohananomitsu High School, yep yep. I look like a kid because of the immortality drug I made, but I'm actually 18. I can use the negation drug to make me look my age, but being a kid makes work simpler since I can move around more easily.
