Okay so I came across this post that says which inner demon would you rather have between these four here?

Sukuna is the first one out effectively immediately. This guy's a literal monster he would take over my body just to go on a killing rampage.

The next one out is definitely Zangetsu. No way in Hell I'm choosing an inner demon that has a hobby of outbursts and quick literally puts my life in danger when he takes over. You have to be out of your damn mind if you think I'm choosing him.

While we're at it get Kurama the Hell up out of here. It's already bad enough I need strong chakra reserves just to contain him like Kushina and Naruto but be friending him will be extremely difficult because most of the time Tailed Beasts like Kurama will openly hate and disrespect you and I'm not Naruto so I won't be able to Talk no Jutsu him into befriending me.

Which is why in my opinion Pochita is the only real logical choice at the end of the day. Not only is Pochita cute but he actually cares about Denji but right from the start he's been nothing but a supporting companion for the human he's inside of. He also is actually not a misanthropic and isn't willing to go on killing streaks and actually cares for and respect Denji and other humans so yeah I'm choosing Pochita.

But let me know in the comments below who you picked.
