天川 瞬

Natsuhiko's father. Deceased. Age 32 at the time of death.
A Rank B Aptitude, Ability Level 4 Communicator, an extreme rarity before the dawning of the Grand Communicator Discovery.
His wife, Miyoko Tenkawa, bore their only son, Natsuhiko, but when the child was only 5 years old, Shun passed away, leaving him a letter and his beloved watch. The details of Shun's death were not spoken of, but it is easy to imagine due to his status as a high-level Communicator. He accompanied Miyoko for a long time, and since she desired the reputation of a genius physicist, he joined her research team in Rokumei City's Parapsychology Research Center as Communicator S. Together, they contributed many advancements to the dawn of BC research from a physics approach. Those who knew him were under the impression that he was aloof, but the passion sleeping within his heart could be seen from his final letter to Natsuhiko.
