19 Need ideas for his peerage members

Hey guys, So when Issei hits lvl 100 the gamer ability will give him this skill:

[Fiction Adaption]- Active- Description:

This ability allows the user to jump into a fiction world in at any area or timeline. Can jump in the fiction world 3 times before being called back to dxd. Can only stay in the fiction world for 3 weeks. Cooldown 1 month, which starts when ussr returns]

So yea he would be allowed to jump into any fiction world so anime games or wuxia lol.

I already decided on his other peices. Just need the pawns, ohh yeah and it says on the wiki that female pawns seems to only used 1 pawn peice, so we are going with that.

Heres what I got so far.

Pawn 1: Nymph- Strategist and recon- From heavens lost property - Anime

Pawn 2: Yoko Littner-Sniper-From Gurren Lagann-Anime

Pawn 3: Shalltear Bloodfallen-cuz shes an OP vampire- From overlord- Anime

Requirements are they must be female and have a kinda harsh backstory so Issei can help them or can be programmed like shalltear and the new genderbent female cast of overlord wahahhahahaha.

So post your choices and tell me why lol
