Join the table with Valkyries this summer for a feast of mouth-watering food and heartwarming memories.

On this wintry day, I'll stay with everyone at Golden Courtyard to do adorable things and create special memories, and then we'll embrace the new year in our unique way. Haha, does this sound ceremonious? After all, I want to create more such wonderful memories with every one of you, because I love you all ♪

The Equipment: Living Forms, or ELFs, were created over fifty thousand years ago to assist humankind in their combat against the Honkai—the decay. With the project's success, the ELFs soon became sentient, compelling humanity to treat them as near-equals. However, when the Ninth Herrscher laid waste to the planet, almost all traces of ELFs vanished into the Sea of Quanta's endless abyss.

Yet, there seems to be a bubble universe where the ELFs' fate has taken a brighter turn. Here, they live peacefully among humans and attend a specialized institution, ELF Academy, where they study as if they were human beings themselves. From Selune's Elegy's chuunibyou tendencies to Blood Embrace's "gangster" shenanigans, the peaceful environment of the academy is guaranteed to provide relief from the depressing state of the main universe.

This was the much-anticipated perfect vacation for everyone. On the luxurious spaceship St. Freya heading toward the moon, we could enjoy this rare and relaxing journey to the fullest — or so we thought.

Mysterious shadows, sudden weightlessness, disappearing items, glaringly faulty alibi... Is the culprit among us?
