Sakuya Kumashiro (神代 佐久耶, Kumashiro Sakuya?) is a character from Tenchi in Tokyo.
Sakuya Kumashiro has been rated 3 on Temangu High's "Must Have List" by her male classmates. However, it is newcomer Tenchi Masaki that gets her attention. On one of his first days, she chooses to sit next to him at lunch, much to the envy of the other guys. Over the course of the series, the two become closer, culminating in the school carnival, where the two share a kiss while Ryoko is watching, causing Ryoko to run away for much of the series' remaining episodes.
Sakuya has strong feelings for Tenchi, and, in the end, her love becomes so strong that she can't bear to be without him. This only gets stronger when Sakuya has a great realization near the end of the series. Yugi keeps a close eye on her, and Sakuya seems to be involved in her plans.
Sakuya goes through a big change when, in a later episode, Tenchi realizes that Sakuya has never spoken about her home, her parents, or anything about her past. Sakuya brushes off the question like always, but this time she becomes aware of the fact that she can't remember anything about herself. In her life, all that has mattered is Tenchi, and she hasn't thought of any of it.
Sakuya begins breaking down, and clings to Tenchi even tighter. The two spend a great deal of time together, and Sakuya tells Tenchi she loves him, asking him if he loves her. He is unable to answer for the time being, and wants longer to think about it.
