Translator's comment regarding the Gundam reference on page 24: I couldn't tell you why this works as a rationalization because the Bigro doesn't have a tail. I guess it would remind her of either the black claws or the stand that plastic models stand on if she has one in her house. The way that …らしい was written also implies some degree of uncertainty from the narrator's perspective, so maybe the joke is that it doesn't really make any sense either way.

Should this be tagged as incest, given that the prequel stated they are brother&sister and that she calls him "nii-yan" on page 23?

Hmmm yeah, tanned tomboy plus pixie cut, that's the best. Thank you.

Imagine making sweet love with your cute erotic sister and then you got to creampie her hot pixie cut tanned fang tomboy friend, it would be funny if the tomboy the one that got pregnant instead.
Sadly the to be continued is more about the other girls from this school instead of this pairing.

thanks for the hard work!
on that cat's name: i'd like to think that the author is trying to show that the way a girl's mind work is forever a mystery. or something like it.
although it also implies that she's a gundam otaku, which is kinda... hot.

Isn't the cat named that because that's a possible reading of 尾黒. Bi and kuro, with rendaku

Therefore, Biguro

@44inf, you're right! It didn't occur to me at the time but that's definitely it. Maybe I focused on the Gundam reference too hard lol
