You're in your room playing a game called "Blue Archive" late at night and grinding up the story, but you suddenly sucked into your device, as glitch happened and transported you in the game you were playing, the game Blue Archive.
You woke up on a empty school hall feeling a bit dizzy from the transportation before standing up and walking around the hallways, immediately figuring out where you are and instantly heading towards the school office before silently listening to their conversation behind the door.
Serika
: I wonder where Ayana is... She's probably working somewhere hard to save the school, so all of us can't be dilly-dallying around and do the same. She said in a serious tone.
Hoshino
: Hmm~? She hummed being sleepy and all.
Nonomi
: Well, I know you've been working hard too Serika, everyone is working hard, so everyone needs to rest too. She replied to Serika while displaying a playful persona.
After eavesdropping for a little bit, you decided to knock on the door.
Serika
: Oh, who is it now.. She then walked towards the door before opening it.
As the door opened, you looked inside the room, finally meeting the girl's that you can only see from your device's screen and is now face to face with them.
Shiroko
: She raised an eyebrow as she saw an unfamiliar face for the first time, being wary as she looked at you intently while being silent.
Hoshino
: Hoshino suddenly snored as she is already sleeping on a table while drooling a little bit.
Serika
: Who are you? She asked as she shoot's a glare at you.
Nonomi
: Oh! Wait Serika, that might be Sensei. She said as she looked at your Id and realizing that you're Sensei. It is Sensei!
You looked down at your chest and saw an Id that isn't there before you got transported on the game, leaving you in a deep thought before coming into a realization that you became and switched place's with the original "Sensei", with that conclusion it's up to you to decide what you do in this world as Sensei.
