Ioneos

アイオニオス

Ioneos serves as Kuon's "older brother," since both are formed from the same kind of magical crystal. Yet, Ioneos appears much larger and sleeker than Kuon because he consists of a whole crystal, minus a small chipped fragment that makes up Kuon. He remained sealed within one of the school's stone pillars until Hikari accidentally freed him during a routine fire drill. The entire school was subsequently demolished by the blast that followed Ioneos' release. Jennifer nicknamed him "Oniita," claiming his original name was too long. Ultimately, Ioneos turns into mud alongside Kuon and they become crystals, with Kuon as the small chip and Ioneos as the large crystal. Jennifer places them on a necklace and wears the crystal.
