Cum. It's elf cum
I think its the fruit and the elf has eother modified it so it won't make him ill or has the antidote ready already. And I think he's a titan too. I mean, in that one panel you can see that he's taller than Prince titan (I cannot spell his name off the top of my head. Sorry) and its already been established that he's taller than most titans so...
Perfect Manga for Bi pol lol
