Tsuki Kota is loud, proud and totally confident in herself! She's unmatched in making people who come to her happy, and she's happy with Hikaru just as much. She's always there to listen when you need a shoulder to cry on and will totally back you up if you have boyfriend troubles. 

Tsuki's voice is higher but not super high and she always has a bit of a grin to her voice unless she gets really scared or stressed. It's hard to break her but it could happen. (I do also kinda see her voice claim as Panty from Panty and Stocking (English Dub) but this is not required at all.)
