This occurred around the time Guren vanished.
There was not a single trace of the boy... His phone, his belongings, and the girl with teary eyes were all that remained.
She took a step forward, hazy and unsteady. She walked up to the rooftop door and went downstairs. She walked into the classroom, carrying what Guren had left behind and her bag. It was already time for class when Hikari entered the room, and the teacher was already talking about something.
"Sekaijou Hikari! You're late! Where have you been all this time?"
"..."
She was carried by silence. Hikari walked in and out as if she didn't hear anything, her eyes dead black as if it had already left life behind. The teacher was so taken aback that she didn't know what to do; all she did was freeze that moment. Hikari, the proper, prim, and 'Role Model' of all the students, did something unruly in front of everyone for the first time. Hikari, on the other hand, was unconcerned. She paid no attention and continued on her way home. All she could think about was seeing Sakura and telling her what had happened.
A case of literary theft: this tale is not rightfully on Amazon; if you see it, report the violation.
As she approached Yuiga's house, she noticed a woman with long black hair and the features of a perfect, hot mature lady. And she shifted her body towards Hikari, revealing a flawless appearance. Long lashes, round crimson eyes, a pleasing pointy noise, and a thin face with rosy red lips. It was Guren's older sister, Sakura.
"Hikari, where is Guren?"
"Sakura, big sis... Guren was..."
Sakura made a silent pause and closed her eyes after hearing what she had heard, not even allowing Hikari to finish. And after a few moments, she opened it and responded...
"I see... So the dreaded 'Fated day' has already arrived, huh?"
"Yes... Sakura-nee, I'm sorry I couldn't even warn him about this... I failed as his 'Overseer'!"
Hikari said this in a sad, weak, and lifeless tone. She called herself an overseer.
What could they have been talking about?
"It's okay, Hikari; we both know this will happen at some point... It's not your fault."
"Sakura-nee..."
"Hikari, brace yourself; from now on, nothing will be as simple as it used to be."
"Yes! Great sister, Sakura!"
What are the implications of their words? Only they know...
In the meantime, back at school, in the faculty office...
"Hmmm... The time has come, hasn't it? Hmph! Better not let my Guren be hurt; if even a small portion of his skin is injured, Fantasia, I will completely destroy you!"
A beautiful lady was shadowed with a domineering aura. And, as it was revealed, it was...
Shizuru with a beaming smile.
