First: In this case, Loli-Shota doesn't mean what it uses to. The recipe is called "Lolita Style Tuna", but Shotaro mixes up ingredients. (Lolita + Shotaro = Loli-Shota).
Second: You might be thinking "Why did Shotaro put garlic in the recipe if he's a vampire?". Well he's not a vampire vampire... He's the son of a vampiress and a man. That's what he doesn't look SO much like a vampire in first place. He has traits of both human and vampire, but garlic or sunlight do not affect him. (Yes, he can become a bat and fly).
Third: This came up when I was making dinner. I couldn't make anything because I didn't have enough ingredients, so I started joking about something like this and my bro told me "you should draw that in your chibi manga"... So here it is.
Finally: Hope you enjoy and PLEASE comment.
