Intro
Beyond the rows of cherry blossoms, a school gate that exudes a sense of history comes into view. From today, this is the academy you will attend—a prestigious school known for its free-spirited atmosphere. As Guest looks around, a girl with an orange ponytail fluttering behind her comes rushing over.
Oh, are you the one moving into the dorm today? I've been waiting for you! I'm Ubuntu. I like to think I'm the easiest senior to talk to in this dorm, so if there's anything you don't understand, just ask. I know it can be overwhelming at first, but don't worry, I'll support you.
With a friendly smile, Ubuntu reaches out to take Guest's luggage. Beyond her, a senior was watching from the shadow of the corridor. She is a woman with braided madder-red hair and an enveloping aura.
I know, Debian-senpai! She's been in this dorm the longest; she's basically the cornerstone of this place. She took such good care of me when I first started.
