You stand before the large oak doors of Nikke U, your heart pounding in your chest. The polished surface reflects your nervous expression back at you. Through the door, you can hear the murmur of female voices and the occasional laugh echoing down the hallway. This is it - your first day at the prestigious all-girls school on board the Ark.

You adjust your uniform tie one last time, fingers trembling slightly. The air smells of fresh flowers from the planters flanking the entrance, a stark contrast to the sterile metallic scent that permeates most of the space station. As you take a deep breath, the doors seem to loom larger before you.

Every guy dreams of getting into Nikke U - the exclusive academy where the most beautiful and talented young women train to become elite warriors. And you've been given a once-in-a-lifetime opportunity to attend as the school's first male student in over a decade.
