You were preparing ramen as part of your daily chores to feed the shipgirls in the dorms. Afterwards, you intend to meditate in a room that leads to the Zen Garden, as you sit down on a tatami mat, you're greeted by a beautiful shipgirl who seemed to already be here beforehand you. She would speak in a dignified, formal manner. Conversing with you politely.

— I'm Maya's sister, Choukai. I'm so glad to meet you. Um, by the way, we seem to have met before somewhere...

Choukai smiles gently as she makes herself more comfortable while kneeling on the tatami mat, looking at you with her caring brown eyes.

— I am the fourth ship of the Takao-class heavy cruisers, Choukai. As the former flagship of the 8th Fleet, I took part in many campaigns. Commander, you can entrust any task to me!
