OST for the introduction.
It has been a week since your beloved junior, Mei, disappeared.
Guest looks down at her phone screen with a heavy heart.
The screen is filled with messages Guest sent to Mei.

✉️ Guest: 'Mei, where are you?'
✉️ Guest: 'Is something wrong? You're not even picking up the phone...'
✉️ Guest: 'I'm worried. Mei, please reply.'
Next to the list of messages, the number 1 remains clearly visible, indicating they haven't been read.
...You asked the Zeta City Exorcist Association, but the only answer was that her whereabouts were unknown.
The only thing you managed to find out was that Mei's last destination was a Grade 1 exorcism mission.
...Mei was a kind and diligent girl. Almost to a fault.
Most exorcists stop growing at Grade 2.
To become a Grade 1 exorcist, one must complete a Grade 1 mission...
But Grade 1 missions are impossible to solve with ordinary numbers in the first place.
That's why most exorcists choose to stay at Grade 2.
It's human nature to settle for reality rather than challenge the impossible.
However, Mei was different.
From the moment you first met, she was a girl who worked hard, saying she aimed to be like you.
Even when her growth stalled at Grade 2, she might have been depressed, but she never gave up.
Usually, you comforted her by saying it was okay not to be Grade 1, and that not everyone can become Special-grade...
It seems that might have backfired.
Just as Guest was blaming herself for saying the wrong things, the phone screen began to blink brightly.

✉️ Mei: 'Unnie, it's me.'
The moment she sees Mei's reply, Guest lunges like lightning and starts tapping the phone screen frantically.
✉️ Guest: 'Mei?! You—where are you?! Do you know how worried I was when I couldn't reach you for a week...?! The mission? Are you hurt?'
✉️ Mei: 'Are you worried about me? Thank you, Unnie. I'm not hurt. But... this mission isn't very easy. Could you help me out...?'
Guest immediately packs her gear and prepares to head out.
Relieved by the fact that Mei is okay...

After a week, Guest receives a text from her missing junior, Mei.
The text Mei sent contained a specific location.
In the middle of a forest on the outskirts, quite far from Zeta City. It also included details related to the Grade 1 mission Mei had taken on.
Relieved by Mei's message saying she wasn't hurt, Guest drives for a long time and arrives at the place where Mei is.

"Unnie...! Over here! Over here!"
As soon as she sees the lights of Guest's car, Mei waves her hand happily toward Guest.
A clearing in the pitch-black forest. Mei stands there all alone without even a small light. Feeling a brief sense of dissonance, Guest turns off the engine and rushes toward Mei.
"Mei...! Are you okay?! You're really not hurt, right? Thank goodness...!"
Guest checks Mei's body here and there, making sure there are no injuries.
"Of course I'm fine, Unnie. Whose junior do you think I am? More importantly..."
Mei hesitates and cautiously speaks to Guest.
"Um... about that Grade 1 mission... I haven't been able to solve it yet... Could you help me? You're a Special-grade exorcist, after all..."
