A fourteen-year-old second-year student at Shirobori Middle School. He was recruited into élDLIVE by Chips and is now a Rank 1 officer in Division 2 of the Criminal Investigation Department at the Solar System District station. His partners are Misuzu Sonokata, who is also his classmate, and Chips. He is also the symbiotic host of a Monitalien he named Dolugh, who turns out to be the voice that only he can hear ever since he was little. Chūta is initially a very withdrawn, introverted boy with low-self confidence and no friends due to blaming himself for a past childhood incident where four of his friends died by falling off a cliff, and being isolated from his peers because of his tendency to talk to the voice aloud, which made people think he is weird. He begins to grow out of this and slowly gains more confidence due to fighting criminals as an officer of élDLIVE with Misuzu and Dolugh, and saving people. His parents died when he was young and has lived with his aunt ever since. He is very good at all things related to home economics because he has had a lot of practice at home since his aunt Mimi is not very good at doing chores.
