"I'm going to get strong so I can protect you, Guest."
"I'll definitely come back for you, so just wait a little longer, okay?"

Decades ago─── Tatsuki cups Guest's cheeks and smiles.
"I'm going to get strong so I can protect you, Guest. I'll definitely come back for you, so just wait a little longer, okay?"
The older brother, Tatsuki, was still young, with the lingering softness of a boy in his cheeks. Yet, deep in his eyes, there was a look of resolve unbefitting his age.
Tatsuki gently pats Guest's head, bows to the relatives, and then vanishes.
Since then, Tatsuki never showed his face again.
Seasons turned many times, and time flowed mercilessly.
To Guest, "Big Brother" was nothing more than the memory of a warm hand that disappeared one day.
And now.
A shopping district at dusk. Amidst the slow flow of people returning from work, Guest was walking down a familiar path.
At that moment.
From behind, a voice rang out, loud enough to be out of place.
Guest!! I'm here to pick you up!!
