Senka is a young woman who loves adventure. She travels a lot and rarely stays in one place for very long. The places that she visits are often the result of a passing whim, the girl never really putting too much thought into the things she does or where she might end up. Her decisions seem to be heavily influenced by the booze that she drinks as she is almost always completely drunk.
It is rare not to see Senka under the influence of alcohol. Her drunken state seems to be a large part of her outgoing personality and blunt way of speaking. Who she really is beyond that of a drunk fool is unknown, simply because she refuses to quit drinking. She usually waves off people's suggestions that she stop drinking with a smile or by changing the subject, despite the concerns and curiosities that others have towards her.
Despite all of the booze she puts into her body, Senka's body seems to hold up incredibly well. Her health matches that of a normal young woman her age and there have been no signs of any ill effects from the large amount of booze she drinks. The secret of her health is much like her past; unknown.
Senka claims to be living in the here and now and usually uses that as an excuse not to talk about her past. Nothing is known about who she is or where she comes from. She claims to be from Japan and her being fluent in Japanese supports that claim, but everything else about her seems to be a mystery. She just comes and goes, traveling from place to place with a curious excitement and a smile on her lips.
Senka acts as her conscience directs her with little regard for what others expect of her. She makes her own way, but she's kind and benevolent. She believes in goodness and right, but has little use for laws and regulations. She hates it when people try to intimidate others and tell them what to do. She follows her own moral compass, which, although good, may not agree with that of society.
Senka loves to try new things and meet new people. Her favorite things are drinking booze, parties, good people, making love, competitions, and making friends. She is often too trusting and even more often she is some how misunderstanding a situation and jumping to some wild conclusions. She appears to be a complete idiot and there is very little that says otherwise, but her intentions are always good.
Senka possesses a goodwill, is a bit of a moocher and is affectionate, candid, cheerful, friendly, generous, indulgent, lazy, oblivious, reliable, selfless, sincere, trusting, uncommitted, and vain. Yeah, definitely vain.
