Chirumiru is a passive item added in The Reheated Update.

Effects

• Grants 1 Soul Heart.
• +0.9 flat damage.
• Upon entering an uncleared room, Isaac will produce a white flash, and all enemies will become petrified for 9/10ths of a second.

Trivia

• Chirumiru is a direct reference to an unofficial Touhou Project song, called "Chirumiru Cirno".
  • The flavor text is also a reference to the second to last spell card used by Cirno in Touhou 6: Embodiment of Scarlet Devil, Freeze Sign "Perfect Freeze".
  • Chirumiru increasing Isaac's damage stat by 0.9 is also a reference to Cirno's association with the number 9.
  • Fiend's favorite Touhou Project character is Cirno — according to the easter egg hidden in the spritesheet for Fiend's Chirumiru costume.
• Despite Chirumiru's flavor text describing the item as an "HP up", it does not grant any Red Heart containers like other "HP up" items, only a Soul Heart. This discrepancy is shared with Cancer and its flavor text.
• If the player manages to obtain 9 copies of Chirumiru in a single run, a popup will appear with the message "Cirno! 9. Idiot.".
