Biography
Sotoka is an excitable young girl who arrived to Japan primarily because of ninjas. Apparently from what she had mentioned in episode 7, her desire to become a ninja stems from "family issues" of which she doesn't elaborate on. Shortly after ending up in the same class as Bocchi, she began to assume that she was secretly a ninja, unaware that Bocchi's crippling social anxiety was at play with how easily it seemed for Bocchi to disappear. Despite initially telling her that she wasn't a ninja. Bocchi decides to take her as an "apprentice" under the agreement that once the training was complete, she would become her friend.

As such, Sotoka became the unofficial third friend of Bocchi's and she is often depicted hanging out with them in addition to doing "training" with Bocchi. She often acts as the motivator for Bocchi alongside Aru. While she viewed Bocchi strictly as her master, she had grown to contemplate whether she could be both her apprentice and her friend. She is also there to comfort Bocchi when her chance encounter with Kai Yawara ended up going badly. Whenever she is extremely happy, Sotoka had the habit of picking Bocchi up, often to the point of unintentionally making her faint. She also takes it upon herself to carry her whenever she was injured or tired.
