Random new abyssals just up and appear out of nowhere. At least she wasn't washed ashore like Re did. Godspeed, man. We await for further scans. This story has come far. Such that I forgot it budded off from a perverted fanwork. As for the lack of katakana, it's either an author oversight, for the convenience of reading, or they have acclimatised to Japan (still does not explain Water Oni there, though).

Everyone's speaking normally here for some reason. No Abyssal katakana speech.Now that you mention it...Erm...Who? Never saw her before...Maybe she's one of our new comrades...
