The Devil happens to be a cat

Well, this was an unexpected turn of events. Issei did think Koneko is like an adorable cat mascot, but never did he think she is actually a literal cat girl Rias choose a good one.

And she is supposed to be rook? A walking mini tank, that's a scary thought.

Her tail waves as she is in a sitting position, hear cat ears flatten, she looks downcast for some reason.

It just makes her adorable in his opinion.

The two blondes are also looking curiously at the reveal Nekomata(still naked mind you,).

"A Nekomata, that is kind of rare, Gremory had chosen a rare one there." Mittelt hummed, resting on a bed naked, it seems that the sudden catgirl reveal had spur out all he embarrassment the three had shown before.

A Nekomata, that's what she is apparently, he had seen a lot of those in his ero games, they are essentially catgirls with mystical power. Though wonder how would that mean in real life.

"Guess that surprised you so much you reveal your form," Issei joked, never thought a surprise butt sex could reveal one's heritage.

Koneko murmured something, he couldn't quite hear that, "what was that?"

"It was an accident... that won't happen again," she said in a sad tone, it seems her form have some secrets there. He doesn't really want to **** it because it may be something personal.

But so, this is this and that is that. He still isn't satisfied, he had to pull out just to know what is going on, his pants still has the bulge, and this cat will be the one paying it.
