Connection! The Boy Genius!

The people at Tenkuji Temple have become united once again and are now joined by the Hermit/Edith. They pay a visit to Ryu's grave where Takeru vows that he will come back to life. Meanwhile, after losing to Takeru and destroying his Eyecon by himself, Adel returns to his real body and enters a dormant state. A new client visits the temple, saying that their child is behaving strangely. He is writing long, complicated mathematical equations and singing strange songs. Takeru and Onari go investigate but find something unexpected. Igor's Demia plan is about to be set into motion and a countdown begins. Adel connects with the power source.
