Hanahaki

Hanahaki rolls at 1 in 66,000,000 in the Blood Rain biome, and the wiki says it cannot appear outside Blood Rain or Glitched. It is the middle aura of the three Halloween 2026 auras native to Blood Rain: Rejoice sits at 1 in 700,000,000 and Former Gardens at 1 in 63,000,000, almost level with Hanahaki. Across the 420 auras with a recorded chance it ranks 152nd, and 66th of 135 in the Event tier.

Blood Rain is not a biome you wait for. The database notes that it lasts 10 minutes and is summoned with a Cursed Rune Fragment bought from Fischl's shop during Graveyard or Pumpkin Moon, so reaching it means first catching one of those nights.

The name comes from a fictional illness in which unrequited love makes flowers grow in the lungs, heart or throat, and the in-game text tells that story as a tragedy rather than a curse. The look follows it: a red torii gate with a black top and a mysterious red structure above it stands behind the player, with red flowers wrapped in dark red mist that glitches in size and colour at random moments. Credits go to Lynoxiouszxcs and Oxiseee, the music is mechanical psychosis by VirtuaLIkimono, and it arrived in Eon 1-31 on 31 October 2026.
