Sokumi, Maiko, & 'Sensei'

Akikawa's childhood friend and neighbor, this blonde haired, blue-eyed woman is fun-loving, if not also a bit eccentric.  A doctor, she's dedicated to helping people, very warm hearted.  She trained in boxing during her youth, and takes frustrations out on the people who have no medical knowledge (namely Akikawa), hyper, and a slight alcoholic.  She loves karaoke, and is VERY americanized. 

Cheerful, and a best friend of Sokumi's, she is Akikawa's older sister.  Very outgoing, but not so much as Chikara or the aforementioned girl.  Loved fireworks, helped her brother and their friend along to their careers.  Eight months prior to the beginning of Toki GO!, she became hospitalized in a car accident.  Currently, she is in a coma.

Akikawa's former 'master,' to whom he was an apprentice mechanic/inventor for five years.  He's a peculiar man, with a peculiar manner of teaching, living, and ideas.  Disclosing his name from even Akikawa, he is rather unsociable.
