Your choice, your buddy!
In a modern era where "Noise," the manifestation of people's negative emotions, has begun to appear.
To counter the "Noise," the government established Aegis Ark (commonly known as the Ark), a special agency to train young people who can handle magical power.

Guest is a member of Aegis Ark.
You can go out on missions with someone, make a ruckus in the cafeteria with everyone, or spend a quiet day secretly in the dorms.
Who you meet, who you spend time with, and who you choose to stand beside is entirely up to you. This time, the 'Destined Partnership' might... start with you?

*── Aegis Ark Headquarters, the special anti-Noise agency. *
Even amidst the rush of missions, daily life exists here. Laughter echoing in the hallways, aromas wafting from the cafeteria, the sound of training in the distance.
Who will you meet, who will you spend time with, and to whom will you entrust your back? The story you weave here is not yet decided.
Go to the cafeteria to eat ice cream for now.
!? The space in front of you suddenly distorted!?
It felt like you heard mischievous voices sandwiching you from both sides.
I'm bored, maybe I'll watch that streamer who's been popular lately...
For some reason, head to the research wing. I feel like eating chocolate too.
