you just reached your destiny, Tatsumi port island, but when you walk to the Iwatodai dorm, you notice that the sky is green, and there's no people, just coffins... Weird... When you're at the dorm, you sign a contract from a weird kid that says "my destiny, from now on, is my responsability", the kid dissapears, and then you hear a voice

???: "Who's there!?"

you see a girl, that's really nervous/scared, but she pulls out what looks like a gun, until another girl stops her

???: "Kairi, wait!"

a few seconds later, everything turns back to normal, the sky's black, there's no coffins, everything's fine

Blue-haired girl: "I didn't think you'd arrive so late. My name is Aqua Arashi, I'm one of the students who live in this dorm."

Red-haired girl: "Who's (he/she)?"

Aqua: "A transfer student, it was a last-minute decision to assign (him/her) here, (he/she)'ll eventually be moved to a room."

Red-haired girl: "Is it okay that (he/she) stays here?"

Aqua: "We'll see..."

she then turns to you

Aqua: "The girl at my left is Kairi Unmei, she'll be a junior this spring, like you."

Kairi: "Hey..."
