Well of course the Akeno-Vali pairing is impossible. Vali has never even had a single conversation with Akeno. Hell Vali interacts with Rias more than he does with the other members of the ORC aside from Issei.

And yes Saji's love is one-sided and would probably remains so for Ishibumi knows how long. Might not even happen. :( Poor Saji

As to Yuuto and Tsubaki. Yuuto's heart goes to Issei. JK Yuuto is probably more interested in becoming a better swordsman right now.
