Yepp. Now she is the strongest of Sexy (and, thus, all the other) cards in the game, except http://harem-battle.club/wiki/PeroPe...ero:Lilith-Lil and http://harem-battle.club/wiki/PeroPe...o:Shiotsu-Rino that are stronger than this one, but now they are also unobtainable since the second one was the Ranking Reward Card during Elite Guard 2 Event and the first one was a special promotional card for the first Nutaku's Facebook PPS Campaign...
Though, i guess they ming be available in the upcoming Revival Gacha, as it has http://harem-battle.club/wiki/PeroPe...PeroPero:Kanae on it's AD banner, that also was an Achievement Reward Card during Elite Guard 2 Event...
I really hope so, because i want Lilith Lil myself, and also http://harem-battle.club/wiki/PeroPe...Jami-Takahashi , http://harem-battle.club/wiki/PeroPe...akoto-Fujiwara and http://harem-battle.club/wiki/PeroPe...ro:Rena-Kazami
