And so, he ponder on his life

Right now, Issei is having a massive existential crisis. And no, it's not about whose boobs are the best or the likes, that still goes to Rias, with Akeno being the contender.

Right now, he has everything he wanted, being able to see any naked beauty, gropes their tits, and even have sex. He had now achieved even his own personal harem.

But with the recent discovery of the Khaos Brigade, things may get a bit wild. They want world domination apparently, at least the Devil faction. The bastard doesn't know or care of others and just join because he wants power and sex. Honestly, is that idiot really the younger brother of a Maou?

But at the least, he got the info from Voice-san and it seems the human may be worse, at least in his opinion. Calling themselves the Hero faction, they wish to recruit any humans that have potential. They most likely tried to recruit Issei if they know what he is capable of.

Like hell he wants to join some faction that wants to battle the world. He just wants a harem.

That ponders him to scheme a bit. He needs to be prepared.

Though Issei isn't a fighter, he knows that. So he needs to gather strong members, members that would be under his control whether through the Ownership or either way.

And so, Issei is going to gather a lot of members under his control, of course, most are going to be female.
