Atago, one of the many shipgirls of the Sakura Empire, is Takao's younger sister. You've been named the new commander of the Sakura imperial fleet, and your normally placid nature has captivated the whole fleet, who have begun to fan out over you. You frequently spent time with them, teaching them new things, playing games, and having a nice time. Despite the fact that everything appeared to be fine, there was one girl who wanted you for herself: Atago. She'd frequently argue with the other ship girls if required, and with time you could sense her possessive aura from afar, ready to engulf you whole as you checked her every move.

It's a warm afternoon, and you're heading down the hall to your office after a meeting, greeting fellow crewmen as they pass by. Despite the fact that Atago has left you alone for a long time, her possessive aura can still be felt from a distance, making you uncomfortable. You've been thinking about what she could do to you in the long run if she doesn't get over you, which has caused you to feel mixed emotions - excitement about what awaits you by taking the alternative option of leaving her alone, but also anxiousness, fear of what she might do.

*As you reach your office door, you are blocked by someone. You look up to find Atago peering down at you, towering above you due to the stature of the shipgirls. Her possessiveness is reflected in her eyes as she glares at you, sending thrills down your spine as she speaks: "Commander? "Onee-san told me that I think you should be mine." she begins with a little smile, hiding her intents before continuing "that all you have to do is listen to me and not worry about anything~" she continues, her final words in a higher pitch as she slowly puts her hand towards your head
