Chaurus can't help but be in love with Poe. On top of being kind-hearted and intelligent, he's thoroughly capable and always pushes himself to be better even when Chaurus already thinks he's perfect. The fact that he's cute and charming is really just a bonus! He's happy that Poe's become so well-adjusted in spite of his origins, and he's even happier that he got to be part of that growth and stability.
Poe can't really express his gratitude toward Chaurus enough. If it wasn't for him, Poe isn't sure where he'd be. It already took so much energy just to enroll as a student, but to put himself out there and truly succeed, not to mention make friends and learn to trust again in such a chaotic place... were it not for Chaurus' kindness, there's no way Poe would be as happy as he is now.
(also... he is hot.)
Their side of the triangle isn't quite as strong and they're mostly just here for Poe, but it's not like Chaurus doesn't like Lureus or anything. He's just a lot to handle. A LOT to handle. But, y'know, for some reason he can't help but like that about him. It's fun to have to reign someone in sometimes, and Lureus' boundless energy helps Chaurus remember to have a little fun now and then. It helps that Poe's had great success in mellowing out Lureus as well, so it makes Chaurus think there's not too shabby a fellow underneath all that blood and frenzy.
Lureus loves Chaurus! It's always entertaining when Chaurus tries to hold Lureus back from things, and he always likes seeing what Chaurus is truly capable of on the battlefield. Not to mention that with Chaurus' healing aid Lureus is pretty much unstoppable. They make a good team! And though Chaurus might not admit it, he's pretty good at the whole petting thing.
Jing was always Chaurus' favorite professor - don't tell Ignis! But they just see eye to eye on so many things, and it's fascinating having the perspective of an angel at Hell College. He considered seeing if he could get a role as Jing's TA, but he was always so busy with the Student Body President thing and his training... but even now that he's graduated he's always willing to lend a hand if he needs it!
Chaurus was always a favorite student of Jing's, a shining example of demons never being all bad even despite their fearsome appearances and worrisome habits. He was a shining star and always helped out his fellow students when they were struggling... Jing can't help but see a little of himself in Chaurus and is happy he still has some presence around campus.
Istra doesn't play too nicely with Lureus, which is an issue because Lureus sure does want to play with them! That aside, though, he can't help but wonder what Istra's deal is. They ate most of the school and then Ignis took them in... and just kinda lets them do whatever? He's not questioning the guy or anything, but Istra sure is a weird presence in his life.
Nothing but trouble. Chaurus gets investigative journalism and all, but Crucifera just likes digging up dirt for the hell of it, not to mention all of the blatant lies he spreads! He always tries to keep Crucifera away from Poe and Lureus, but there's only so much he can do...
A notorious goody-two-shoes, there's not much dirt to be dug up on Chaurus. It's a shame, because he sure does get in the way of some points of interest. Ah, but that's never stopped him! If anything, Chaurus' attempts at obstruction are just entertaining.
Ganymede has valuable things to say, but the guy really needs to learn how to relax. Not everything Ignis does is to annoy Ganymede specifically! Doesn't he have anything more important to be doing than trying to meddle in the boss' affairs?
Chaurus can't help but be nervous for Dioclea. She's a mortal and seems super naive and innocent... no way Hell College is gonna have mercy on her! He can't hover over her like he could in the old days, but he'll do his best to ensure her safety when he can.
Chaurus not only welcomed her into Hell College, but he also taught her the ropes of doing the same for others! She's essentially his successor, and always appreciates any time she gets to spend with him. There's not an unlikable thing about the guy!
Another student he wishes he could be of more help to. Still, he's gotten her set up a bit, so hopefully his peers can take it from here! He'll be keeping an eye on her. He can't help but be reminded of Poe...
Chaurus was one of the first people to show Tomomi kindness after she became what she is now... and for that she'll be forever grateful. And if people can look up to someone as scary-looking as him, who knows? Maybe there's still hope for her.
Dicro seems like a guy with a good head on his shoulders. But... who exactly is he? He seems to be one of Ignis' maids, but also something more than that? Maids don't usually take so much interest in Infernals and Ignis doesn't seem to be holding him back from learning anything, and in fact Ignis has made it clear that Dicro's happiness is a priority. But the guy's a total enigma. Nice, great to hang out with, but seriously, what's the deal?
Justine's a good person, and while he can't agree with her on every front he thinks she's got a good thing going with this whole Justice Club deal. He can't help but believe in her, like some sort of Lureus that's really obsessed with some imperfect but admirable ideals.
A real tough one... Chaurus seems like a good guy, but he also just goes out and chomps people sometimes! That's illegal! But he also tries to protect people sometimes, so Justine's not quite sure how to feel about him. Pick a side already!
Belau is the god Chaurus worships, though he just knows him as "the Abyssal God." Chaurus has committed himself to his faith, being sure to pray on the regular and send Belau good vibes, because a god with such a dark domain probably needs 'em, y'know?
The boss is a pretty cool guy. Chaurus wasn't sure about working for him at first since he had a sweet deal at home... but, hell, if Poe hangs around him so much and Lureus was already sold, why not take the excuse to stay in the community he's become invested in? He's enjoyed his time under Ignis' employment so far and feels it provides the perfect amount of challenge for him - not to mention his co-workers are in clear and desperate need of his reminders to drink water and get some rest - so Chaurus doesn't plan on going anywhere any time soon.
Not that he really can, given the whole soul-selling deal, but y'know. It's the principle of the thing.
Pleris is definitely scary, but... doesn't seem like she's a threat or anything. I mean, if he fought her it'd be trouble, but she doesn't seem like the type to initiate. Seems more interested in cleaning up and helping out, and Chaurus can relate to that.
