1) A new member for the church squad... Well it's not a surprise, she is an exorcist devoted. But this also means she will be a harem member. By the way I think it's a missed opportunity here, I would have seen Lint, since she seems related to Freed, more in Issei's peerage than Rias', even if she is with Rias just for the tournament.

4) They could solve their problem (and Ddraig doesn't even know why she hates him) through Issei's D... XD A Dragon King would be perfect for his team, beauty and power.

5) If it is so, it's obviously only for the tournament because he is a guy.

6) No, they are the pieces that reincarnated Issei, probably the achievement of Diabolos Dragon God did a similar thing like when he activated the Juggernaut Drive and he needs to fix them again.
