Tekka is a mysterious swordswoman, who's ability with a katana and fast reflexes are almost unmatched (inhuman even). She tries to kill Tom during their first encounter. Her reasons for wanting the man dead at the time are unknown.

Tekka is stoic in every sense of the word, and prefers to speak only when necessary. She can come off as quite cold sometimes, but deep down, she's a caring individual.

(Note: Her full name is written in the Japanese full-name format, meaning that her first name is Tekka and last name Hirabayashi.)
