"Oh man... You know sometimes you're too playful for your own good." Aiden mumbled as he rubbed his head having gone down kind of hard. Sure this wouldn't effect him much had he been in his more wolf like form, but still human meant weaker. For him anyway. Some demons and monsters might not feel the same effects. Regardless he seemed to effortlessly lift his sister as he got back into a standing position. He dusted her off first and them himself. "No need to apologize." He then said to Mina after a brief silence. "Although I do think it'd be best to gain a bit more control. You looked about ready to try and fight my sister." He laughed as he thought of how quickly things could have escalated. After all not everyone was as used to his sister's antics as he was. 

With things settling down a bit he noticed two more things. A sort of question coming from another male who'd peeked into the hall and the girl who'd greeted Mina now cowering. "Look at what you did Eira? The dude is probably thinking about moving out and you scared her." He said with small, somewhat amused, smile on his face before walking past Mina to Misaki. "Hey. You don't need to be scared. My sister can do dumb things, but she wouldn't hurt someone without a legitimate reason." He said as he knelt beside her to try and ease her nerves. "And sure the scary lady here didn't mean any harm either." He added pointing to Mina with a small chuckle. "I'm Aiden, by the way. You are?" He asked before thinking for a moment. "Oh yeah. You too." He said to Mina. "I need to know your name." They probably all should have learned each other's names. Especially since they all lived like right next to each other.
