Hifuu Nightmare Diary: Violet Detector.

About

Violet Detector, like its predecessors Shoot the Bullet, Double Spoiler and Impossible Spell Card, is a collection of many individual danmaku patterns that the player can choose from at their leisure. In addition to the usual mechanic of taking photographs that clear enemy bullets, Sumireko has several psychic superpowers at her disposal, such as teleportation. The game features all of the characters who debuted in Legacy of Lunatic Kingdom and Hidden Star in Four Seasons, plus Reimu, Marisa, and most of the final and EX bosses from previous games.
