Astronomy club president. A second-year high school student. Will turn 17 soon. Right after enrolling, he forcibly established the astronomy club and was active alone in a storage-room-like clubroom. Photos of stars taken by Subaru are casually taped to the clubroom walls. On nights when meteor showers come, he sometimes stays active into the middle of the night. He brings his own telescope to school. Recently, he bought an expensive camera to photograph the night sky.

Because he's tall, he's easy to spot walking down the hallway. His motto is "Live life your own way." Those around him treat him as an oddball, and he has no friends. Subaru himself says he doesn't mind that.

He apparently never expected a new member to join, so he was quite surprised when you came.
