Kumi Kawamura is a born leader with a strong sense of responsibility and determination. She was the former class president of the Student Council who had been elected every year since first grade. Kumi joined with the Alien Party in hopes of avoiding the responsibilities of caring for kids' problems. Easier said than done. She is the leader and the most independant member of the Alien Party.

Kumi had to fuse with her Borg after she was attacked and killed by an alien. She can use drill-like projectiles from her body painlessly to attack or defend like a Borg.
