Outerplane hosts a Bunny Moon Party featuring a new 3-star bruiser and complimentary bunny-themed cosmetics

Background: A one-year service-transfer milestone becomes an event hook

Outerplane is marking one year of service transfer, and Major9 is using the anniversary as the reason for a themed update. In a role-playing game, an anniversary is a natural moment to combine new playable content, limited-time rewards, and cosmetics because the milestone gives players a clear reason to return. This one-year celebration is built around that formula: free rewards are available this month, the event is titled “Bunny Moon Party,” and the theme includes bunny-themed cosmetics and tasty mochi cakes.

Development: Bunny Moon Party introduces Demiurge Lambda, a 3-star Light Striker

The main content addition is the new Demiurge hero “Demiurge Lambda.” She is listed as a 3-star Light-element Striker-type bruiser, and her self-healing abilities are described as a way to boost survivability. For players, that means the update is not only cosmetic: a new hero can affect team building, especially if a player needs a bruiser who can sustain through fights or a Light-element option for element-based team synergy.

Alongside the hero, the update offers limited-time rewards and “tons of freebies” during this month’s event period. The event packaging therefore targets two groups at once: players who want new roster options and players who participate mainly to collect anniversary rewards.

One clearly defined reward is Monad Eva’s Bunny Moon costume, which can be obtained for free through the login bonus event. This matters because it does not depend on a new hero acquisition or paid purchase; players can log in, claim the costume, and still take part in the anniversary celebration. The same event window also connects the free costume to broader anniversary rewards, including bunny-themed cosmetics and tasty mochi cakes.

Current stage: One year into the service-transfer milestone, the game is in an anniversary reward cycle

At this point, Major9 is using the one-year service-transfer milestone for Outerplane as a live-service celebration rather than a simple commemoration. The immediate value for players is a mix of progression and collection: a new 3-star Light-element Striker-type bruiser in Demiurge Lambda, self-healing survivability, and a free Monad Eva Bunny Moon costume from the login bonus. The broader signal is that this month’s limited-time rewards and themed cosmetics are shaping the short-term appeal of the anniversary.
