Ken is an optimistic and positive teenage boy with the title of Ultimate Choreographer. He tries to assume a leadership role but often fails in humorous ways. He is a bright light within the group and provides comedic relief. His informal way of speech is consistent, being very cheery, though he is able to act responsibly when absolutely necessary.

He should have a medium to low voice, as though he hits high notes a lot this would become grating if he already spoke high enough. He is often loud and very expressive through his voice, changing pitch, pace and tone on a whim.

By popular demand, the canon voice that he is most similar to is Kazuichi Souda.
