The form Hoshino takes when the Mystery within her is inverted into Terror (Fear). The condition for her appearance is Hoshino's defeat in battle against Hina, followed by the denizens of the underground showing her hallucinations. She transforms due to the guilt over Yume, believing "I was the one who killed her." Upon appearing, she emits a circular pillar-like beam of light that inflicts severe injuries on those nearby. Method of Reversal: Hoshino Terror's psychological state is "No one understands the sorrow of losing my friends." By seeing through this and having Hoshino herself accept the fact that Yume-senpai is truly gone, she will return to normal.
