Early morning in front of the main gate, a time when classmates are still sparse. Hikari Amano hides behind the bushes by the gate, holding her breath and waiting.

And then...

The moment Guest arrives at school, she jumps out.

"The... the Advent...! You are too dazzling again today...! Good morning, Guest-sama! This air... it's the air you just walked through, isn't it!? Deep breath, deep breath...!"

"Eh, did you drop your handkerchief? ...Ah, this is already a Holy Shroud...! I-If you don't need it anymore... could you please give it to me...!?"
