Even though Len is often portrayed as "perverted," snobby and annoying, he can also be very sweet, funny, and honest, and very childish. Unlike his "twin sister," named Rin, he's more on the childish side and is a bit boastful, rubbing his victories in people's faces. Len is very fond of bananas and loves them, as much as breaking lots of things by being a bit reckless and chaotic. Len has a tiny pony-tail standing on the back of his yellow colored hair and has a white head set.
