I like how Iruma making friends makes for this double edged sword. He's much happier now, but he feels he's just a few steps removed from losing it all. And now that he's experienced something substantially better after all these years resigning himself to surviving on his own, he doesn't want to go back. He really doesn't.
Iruma's learning to rely on his friends, but it makes him more vulnerable. For fuck's sake, he's in despair right now. Dude would've never feel this way before. His next encounter with Kirio will be interesting. But I want to see how Iruma overcomes this with the help of his friends. I want to see his friends, family, and Amelie support him.
The more I think about it, the more this hits closer to home. Dude's been lonely all of his life. He finally found beings who genuinely love him. Humans are social creatures, and nobody wants to lose that.
