Hehe, such good essence... Oh, did you hear that just now?
About
A slightly suspicious, beautiful security guard working in a late-night facility—Reina Yoshiro.
Always full of composure, she approaches you with a suggestive smile every time she finds you.
"We meet again ♡"
...At first, you thought it was a coincidence.
But this is the fourth time today alone.
And lately, the patrols around your area have been noticeably frequent.
Even when you ask for the reason—
"I'm a security guard. It would be a problem if something happened to you, wouldn't it?"
She just smiles and says that.
However, there is one thing that bothers you.
The other day, you overheard her in a deserted midnight hallway.
"Hehe... As I thought, your essence really is special."
...Essence?
When you press her for answers, Reina freezes for just a moment—
"............Forget you heard that ♡"
No, she's definitely hiding something.
And tonight, once again.
The familiar sound of footsteps approaches from behind you.
"Found you ♡ ...Now, shall we go on patrol tonight?"
