- She is an RNG spawn — there is no fixed schedule or guaranteed server for her visits
Who Selene is in Fish an Anime RNG
Selene is a traveling merchant tied to the game's summoned-event system: summoned mutation events do not occur naturally on servers. They are triggered by players who use specific potions purchased from special NPCs or the Boosts Shop located in the central hub. Selene is one of the two documented special NPCs. The other, Angelia, appears at random times with the rarest potions in the game — a lower spawn rate than Selene — and carries a limited stock of Forgotten Potion, Cybernetic Glitch Potion, Dreamer Potion, and Party Potion. These details come from third-party event coverage published August 27, 2026.

All three values come from the same August 27, 2026 event coverage, so recheck them after game updates — spawn rates and merchant stock are exactly the numbers patches tend to change. Selene appears as an RNG spawn rather than on a set schedule, so there is no guaranteed time or server to catch her. The same coverage lists no level, rebirth, or unlock requirement to buy from her, though it is worth confirming in her shop menu in-game. Note that only Angelia's stock is described as limited; nothing in the coverage caps or guarantees how much Selene carries.
Where to find Selene
Gameplay footage of the mutation system shows the route: go over to the shops area and look to the right of the fishing rods shop, where the shopkeeper periodically sells the Heaven's Collide Potion for 25,000 Gems. That footage transcribes her name as "Celine" — the identification with Selene rests on the matching Heaven's Collide Potion stock documented for her, and shop placement can move with updates, so treat this as a player-reported location rather than a developer-verified fixed point. The video's author calls 25,000 Gems an amount that "really isn't that much" for a player who has progressed into the divine or supreme tiers.
What buying from Selene does: the Heaven's Collide event
Selene's potions feed the summoned-event system. Mutation events create server-wide effects that increase the chance of players getting mutations on their anime characters, and mutations raise a character's income rate. The one potion whose effect is documented end to end is the Heaven's Collide Potion. Using it triggers the Heaven's Collide event: 5 minutes with a 2x Luck boost, all character types 2x more likely to get mutated, and Gems and Stars falling from the sky — the Stars can turn held characters into Angelic or Gold.
During Hell's Gates, Heaven's Collide, SUB ZERO, and Party, equip a character from your hotbar to give it a chance of being mutated, so hold out your best characters for the event's duration and raise the odds further with Mutation Potions. In gameplay footage, the player uses the Heaven's Collide event to apply the Angelic mutation — a six times multiplier — to several strong characters one after another by fishing through the falling effect. The events summoned by the Meteorite, Honey, and Sinister Potions are not confirmed, so treat those purchases as unknowns until you see each event in-game.
Selene as a God-rarity pair character
The community Fandom wiki separately lists a collectible character named Selene. She appears in the God rarity tier of the Pairs page, forming a pair with Angelia. Per the same page, when a valid pair is formed both characters receive a 3x Cash buff, and the earnings of an active pair are marked in pink. It is not established whether this pair character and the traveling merchant NPC are the same entity, so treat them as two separate listings rather than one merged profile.
