The story is so unrealistic that it's hard to take seriously.
Yeah, i know. Which is why i think this story is so unrealistic. If they are going to make a story that happen in our world, than they should make a story that follow how our world work. There's no way that if a girl like her would appear in our world that she could show her power to a government official just like she did. If it would be reality, it wouldn't be long before she simply disappear and if by bad luck the knowledge of her was leaked, than the biggest war we ever had would start. Humans would be ready to do anything for a chance to get their hands on a new power like magic.
The story could have been decent if it wasn't of all the needless fan service, The fan service get bad enough that the author hold back behemoth evolution just so he can stay with the elf longer for more fan service... Seriously, i have seen hentai that had more story than this... Anyway, unless you come here for fan service, stay away from this it isn't worth your times.
Honestly it began to be cringe when she began to sexually molest a kitty!!!
And yes, I have stories be ruined by fanservice and harem a lot...
