Better put Roygun in "Shown interest in him" for now.. She is even older than Kuroka.. But I admit that live in Issei's house is a point in his favor..

The only possible(in my opinion) NOW are:

-Bennia is fan of Issei and is in the ORC(no girl is safe of Issei here).. more easy for her than for Tsubasa..

-Lint.. I see an interesting case... In two Incomplete volumes.. Similar character to an old enemy Freed(a possible familiar).. Another user of the Incinerate Anthem, in Rias team(we will see more of her), a possible familiar of Freed.. All that in the Vol 22... and in the spoilers of the Vol 23, no, she isn´t familiar of him,  Ishi use a different past in her(less simple)..

About another girls... Nothing against these girls.. But I need see more revelance for believe in that.. Mirana is Asia as angel and with Tiamat problems with Ddraig, no...
