Good boy

"Have any ideas about that guy ?"

"I can sense a powerful aura from him. An aura that likes a Satan"

"... he is a devil, or have a devil piece inside, and strong enough to be a Satan"

"Not with the last. He has an aura similar to a Satan, but not equal to him"

Issei's theory is Vali is either a Satan's heir like Rias or someone come from a Satan's clan.

Suddenly, his thought is cut off because a cheerful girl with a pretty face and wearing magical girl costume appears and smiles at him.

"You must be Crimson Dragon Emperor"

"Sorry, you are ..."

"Sona-tan's sister"

How many times the shock attack him ? First White Dragon Emperor, now Sona's sister, Serafall Leviathan - in other words, a Satan.

And another one behind him.

"I always want to meet you face-to-face, Crimson Dragon Emperor ... or should i say, Hyoudou Issei-kun ?"

Crimson hair like Rias, and the unbelievable aura.

He is Rias's brother - Sirzechs Lucifer.

"so, what do i do to bring two Satans here ?"

"Relax. We just want to ask you something"

"... isn't it too weird that you need to ask me instead of ordering ?"

"This is something you mustn't do"

"... don't fight White Dragon Emperor in the meeting, even if he is at Fallen Angel's side. Is my guess right ?"

"Thanks you for knowing that"

"You can just let President tell me"

"Rias will let you fight him when the meeting is over. She truly hates fallen angels and its allies"

That's true. They assaulted Asia and ruined Kiba's childhood. With Rias's personality, she will not let anyone dares to touch her servants go easily.

"... i will try my best to not make a fight with him, but if he or his allies go over my limit ..."

"I know, just please keep your head cold enough for the peace"

The peace, huh. He is the partner of one of two dragons that used to nearly bring the world to its end, and the one ruined some girls's life for selfish goal. He doesn't think he has the right to stand for the peace.

"Don't become so sad Crimson-chan, you saved this town from that bastard fallen angel, that's enough to proof you are a good boy"

Being praised by Serafall, Issei feels better. Also, her magical girl-style costume make his dominant rises, but he knows touch her now will be his end.

"Does President know you two are here ?"

"No. Please keep this a secret. We don't want to make our sisters worried"

"Sure"

As they leave, Issei goes to Sona's team with an idea.

Seeing Issei, they (except Saji) are affected by the mark that makes them desire to be his plaything but try their best to keep it secret.

But he doesn't come here for that as he uses Mind Stone on them again.

"Except Sona, one by one tell me who you love, or the kind of male you love"

By that, he knew Vice President Tsubaki Shinra and the blonde bishop Reya Kusaka love Kiba, the knight Tomoe Meguri loves younger boys, and the other white hair bishop Momo Hanakai, rook Tsubasa Yura and pawn Ruruko Nimura love Saji.

"Alright, that's over. Return to normal and forget this conversation"

Issei just needs to hear their crush so he can give them chance, as a payback to Serafall's praise.

Only for today, he will be a good boy.
