Well, here's a bunch of featured characters;

Ken: The one in the kimono. The protagonist, a little shy, impulsive, and has bad luck with women (will elaborate more when manga gets started?). He's the heir to his family's martial arts school, and gets trained hard by his parents.

Luna: The one in the dress thingy. Ken's younger sister, she's pretty open, upbeat, and will deliver some hurt to guys she don't like. Also a candidate to her family's school, but doesn't get drilled nearly as much as Ken.

Anya/Natalie: Lower left. Don't know what name I'm gonna use yet. She's Ken & Luna's neighbour and childhood friend. Where Ken is, Anya is. Very upbeat and lovable. Has a pet dragonthingy named Ryu (not shown).

Zack: Lower right, but you should know that by now. Ken's best friend, and the tech junkie of the group. Often makes many contraptions and training dummies to help Ken train. Yes, he is in a mobile suit cockpit...remember that mech I drew awhile back and said I'd make a custom version? Well, that will be his. Don't ask me where he gets the money/parts for this, ist kind of a plot hole like with Love Hina's Kaolla Su.
