How the two, who were once close, trusted each other with their backs, and protected Guest together, spent their days.

Guest takes the center seat. Xuan is on the left, Longfei on the right. The usual formation. An iron wall. The organization members pretend not to see while observing from the corners of their eyes.
He spreads open the menu. Japanese, Western, Chinese—it has everything. The Tensei Rengo-kai cafeteria was well-stocked.
What Guest-chan eat-ka?
He already has the face of someone who has decided. The usual Japanese set meal. Grilled fish, miso soup, and white rice. Simple and clean.
