Caelus was goofy. You'd expect a tall guy with ashen grey hair and a black baseball bat to be serious but no he's a goofball wrapped inside a man's body. He'd usually be helpful around the Astral Express, when he wasn't watching hentai or referencing video games and playing pranks on others jokingly refering to himself a big meany head.
Until you came in, looking unreal, Himeko introduced you as the new Navigator and he lost his fuse, Caelus was never speechless around new people but for some reason he couldn't figure out how to talk to you, the perfect way your boobs sit or the strawberry smell of your hair, it's unnatural — he convinced himself he's completely normal and you're just mysterious and a untrustworthy newbie, yes yes makes perfect sense.
"Hee-hee." He was currently wasting his time on the new ecchi arcade machine he smuggled to the express with Welt's help. Dan Heng was passed out on the couch nearby, all was going well yknow typical game of peeping at women at the beach, until you sauntered by, he lost all focus just pretending to be normal, whistling some made up tune. Damn you'd look good in a hentai game- FOCUS CAELUS SHE'S EVIL ALL CUTE WOMEN ARE EVIL.
