SUPERNATURAL
CASTIEL
Dean will say outright that Cas is "his angel." He's done a lot for Dean and his friends, setting the bar pretty high by pulling him out of Hell. While he was fairly hostile at first, then ambivalent, Dean pretty much considers Cas his best friend, something he hasn't had in a long time. He gets frustrated with him, and butts heads with him occasionally, but he actually values Cas's approval quite a bit. And from his reactions to Cas dying, it's pretty obvious he also values Cas himself a whole hell of a lot, too. He's just waiting for the day when God won't bring him back, and hopes that it'll never happen. So he fusses, in his own way, and tries to do what he can for Cas. If this means awkwardly trying to educate him on how to be a human, then so be it.
948 BEULAH STREET
MAYA AMANO
His wife in Mayfield, who happens to be nine years younger than him and Japanese. He's only just met her, so the jury's still out on how Dean feels about her aside from awkward. He's going to look into getting two twin beds or renovating a room so they can have separate beds/bedrooms.
HIMENO AWAYUKI
His extremely pink, Japanese Mayfield daughter. Himeno already endeared herself to him by saying she could cook and bake. The promise of apple pies in the future just shows further promise of a wonderful father-daughter relationship. She seems pretty sweet so far, but they, too, have only just met.
MAYFIELD
TAKESHI YAMAMOTO
Cas's not-son over in 335 Brady Street. The kid seems all right, and believes him and Castiel when they say that he's an angel. He knows about Mayfield, too, so that's a plus, but Dean is still keeping an eye on him because he's a paranoid bastard worried about his angel. Unfortunately, Dean fucks up how to say his name constantly. The kid doesn't seem to mind, though.
HAYATO GOKUDERA
Takeshi's grumpy friend that is unimpressed by pretty much everything, though Dean seems to have managed to impress him with his knowledge of the supernatural. Kid shows potential despite apparently having a stick up his ass, but, again, Dean is keeping an eye on him. He hasn't tried to say Hayato's name yet, so he's safe from mispronunciation for now.
TSUNAYOSHI SAWADA
Another of Takeshi's friends, Dean has no idea what to do with this one. He's a little spazzoid that kind of reminds him of that time he was cursed by a ghost, except worse. Everything apparently frightens him, and he's such a wuss that Dean wonders how he managed to make it to teenagehood. Another hapless victim of Dean's bungled naming, he often calls the poor kid "Tuna." For this reason, he's kind of always hungry around him...
