S01E10 — End

Keita heads off to rescue Kuro, held as a prisoner by Hiyou while Makane runs off to rescue Kakuma as he was held hostage by Reishin. Shinobu, however, survived the attack by Keita back at the beach and tries to drain off his Tera energy while telling him that she was responsible for killing Keita's mother due to her miserable life under the Doppleiner system before and after making a contract wit Hiyou. After Kuro and Keita were able to synchronize and defeat Hiyou, Shinobu dies as she was not able to tap into Keita's Tera to make herself stronger. When the two leave the cave with Shinobu's body, Keita encounters Daichi who he knows as Sawamura before he collapses due to coughing up blood.
