Maybe because we had Irina as Issei team angel and the vol 23 events... Is better this than nothing to apologize with the old ORC/rias peerage members for that..

Lint in the harem? I suspected that since the begin, from the church quartet mention.. Then she was confirmed as angel(long lifetime).. Even if Rias losed the tournament she is a longinus user, she will continue in the serie.. I think that Shin dxd 1 confirmed her in the battle against Nyx.

We will learn more about Sigurg Institution in the future.. I remember Ishibumi mentioning something about that.
