Takeru Takemoto is this series' main character. He comes off as a lazy and unmotivated teenager, but is really just unsure of his place in the world. He was the one to find and name Hikari in the first episode. He can transform into a powerful being with superstrength and sharp appendages. He has an apparent love interest in Hikari, blushing and getting flustered when near her, and eventually admits he likes her.
