EveONI:
Blood Moon.
A blade against the night.
One swordsman.
Three guardian seals.
Under a red moon, lanterns burn through a maze of timber galleries. Akira faces an iron guardian, a frost sorceress, and a six-armed sovereign. The board and the battle tell the same story: a matching rune cluster becomes a strike, and the awarded result becomes progress through the guardian’s curse.
Read the game storyRead the board
Five or more matching runes connected horizontally or vertically form a winning cluster. The 7 × 7 board is evaluated once per spin.
See the technique
Flame, Moon, Thunder, Iron, Gale, and Frost each have a distinct sword technique. Larger clusters bring stronger visual technique tiers.
Follow the trial
During the free-spin feature, accumulated wins move the battle through three guardian seals. Each strike shows its part of the awarded result.

Three faces of the night.
Three distinct silhouettes, weapons, and chapters in one free-spin battle.
The Red Oni
The iron guardian. Heavy armour, a towering club, and the first seal of the trial.
Yuki Oni
The frost sorceress. A pale silhouette, flowing robes, and a long ice lance.
Blood Moon Lord
The six-armed sovereign. Moon blades, an ornate mask, and the final guardian seal.

The Blood Moon Trial.
Three scatter seals open 15 free spins. Power starts at 1× and rises by two after each winning free spin, applying to the next turn. As the trial unfolds, Akira’s techniques progress from Initiate through Awakened and Eclipse Art to Moonbreaker. Seal all three guardians and the remaining spins continue in Afterglow.
Akira’s HP shows the remaining free spins. Guardian seals, technique effects, and Chronicle cosmetics present the result; they do not add a separate payout. The feature ends after its spins or when the round reaches its win cap.
The next chapter is getting closer.
