But if that is the only way he can live, there are worse things to do than make them cry for a bit before clearing out the Phantom inside them and making sure they will never be targeted by Wiseman ever.

For most gates, their despair has to be initiated by something more than giving them a helping of insults. It can range from destroying an item, destroying a house, or killing another person. There's no way Nito would murder someone to get his fix.

Watched Episode 5 and 6 of Kiva. I just love the creatures his other forms are based on, and the 1986 storyline is great too. I like Wataru and Otoya. Nago is pretty sweet too.

I believe I am going to try go stop juggling and finish a series at a time right now. I am going to continue with OOO and move on from there.

That was a plot point in Nitou's introductory story arc, wasn't it?
That, since no Phantoms were being spawned, there's a finite pool of them for him to feed on?

Also, only Medusa can identify Gates. Not Nitou. Not Koyumi. Not Haruto. He can't drive them to despair because no one else can point them out to him.

Well then if he just avoids the ones he'll land homeless or have to murder for and just go for the ones who need items smashed he'll be fine?

He can just recon, find out who the Phantoms are targeting, work out how they are driving them to despair. Kill the Phantom, eat it then go drive the person to despair and take their mana.

Except it's only Medusa.
And she's Haruto's current target.

And your theory only works if Nitou is a complete monster, which he isn't.

Nitou driving Gates to despair goes against his moral code. I'm not sure if you're willing to endanger others' lives for the sake of your own, but Nitou is not. His conflict arises from the fact that he needs to consume Phantom mana to survive, and their finite nature means he can only survive for so long before Chimaera eats him. However, he cannot make Phantoms because it is against his moral code to endanger other humans for his own benefit.

I'll have to take your guys words for it, at the current point in the series I am Beast is still selfish and driven only by his will to survive.

I figured you had finished Beast's story arc. My bad.

Nope so far he's introduced his backstory (which was really cool), taken a trip inside someone and turned down Haruto's offer to cure him with vague homophobia.
