Suspecting that Togo may be somewhere behind the wall, Sonoko brings together everyone's transformation cellphones, containing a new Hero System that won't affect their body functions but instead ties its barrier functionality to the Mankai Gauge, which will empty if they use the Mankai form. Once again transforming into heroes, the girls venture beyond the wall and detect Togo's signal coming from a mysterious black hole. Using Sonoko's Mankai form as a ship, Yuna ventures into the black hole while the others hold off the pursuing Vertex.
Expending her barrier to survive the hole's gravity, Yuna's spirit becomes separated from her body, during which she discovers fragments of Togo's memories. Due to her actions causing flames to leak out of the hole in the boundary she left, Togo agreed to be a ritual sacrifice in order to suppress the flames, having Shinju rewrite the memories of Yuna and the others so they wouldn't go after her. Yuna soon finds Togo trapped in a construct with a sprit surrounded in flames behind her. Despite the risk to her own spirit and body, Yuna pulls Togo out of the construct, taking on the full extent of her curse. As Togo is safely returned to the real world with the flames stabilized, Yuna keeps secret the marks now embedded in her body.
