On the subject of Japanese names (and me not wanting to make a new topic), does KNT ever mention the last names of the Cats? Also, does it ever mention alternate names (Like in Pizza Bird Delivers, for example)?
The series doesn't have so much sense about that... I've noticed that the people just know the Nyankee by their battle names (Nyankee Ichi, Ni and San Go).. In the episode 02 Pururun covers her mouth after almost say the name of Sukashii in front of OmiChan... Anyway, Karamaru knows the real names of the Nyankees (That's the reason of why Pururun gives them fake names while Karamaru was working at Pizza Cat)...
Anyway, Karamaru seems the only one of the bad guys who knows the names of the cats (Yattaro, Sukashii and Pururun)... All the other people (Including Koon and Gennarisai) just know them by the battle names... About last names; any of the characters have a last name, at least I don't remember any...
