Kuga = Brown girl.
Akira Tenma = That girl who's always wearing armor and saved MC and his sister from that fatso from class D.
Tsukishima = Introduced as the third player, is roleplaying as a netorare villain but can't even steal MC's CF.
The rest are yet to appear on the manga.
Sera will show up in the next chapter.
I knew Kuga, cause dark-skinned, tomboyish petanko girl is up my alley even if I am not fan of short hair. Plus she was mentioned in the latest updated chapters.
Wont lie, would need to re-read to see who the Akira is, cause the info you gave doesn't really help me much. Thou if she huge titied - I don't really care
.
Third player helps - cause its the title of the chapter so easy to check - blond wanna-be player.
Can't see the rest if they didn't appear in the manga, so wonder how they would look like, especially Sera supposed waifu.
My preference is small tits and as personalities aren't really that visible yet in manga so looks is mostly what I go after for now, so thus far I liked only Kuga, that dark hired girl who was jumping in the 43th chapter cheering on, and IIRC that one girl who "investigated" when some bad dudes wanted to hurt or out-right kill MC and a girl he was doing some tests with or something. IIRC that girl also had small rack, thou I am not sure if its not the same one as the cheering one lol.
The whole manga is kinda lame thus far, not sure if its cause of the premise/way its written/draw, or is it bad quality translations that seems to be all over the place especially in some of the latest chapters. Its like there are a lot of "hidden things" but they are so random and so slowly explained, that I don't really have any hooks to keep me interested. To the point I wonder why I even bother reading - probably to lazy to remove from bookmarks lol.
EDIT: Ah just re-read the promotional stuff, cause curiosity won. That petanko girl he was testing with is indeed the jumping one. Just that her pony-tail is magically far shorter than it should be, seeing how her default hair is quite long double braids. And also the petanko investigator girl who I also liked, is actually the Kirara girl you mentioned (as his "rizzed girl from 2nd class A).
