Ririko: Isn't Your Shikigami Just Trying to Sleep with Its Master?! The Path from Great Aragami to True God

Uesugi Tetsu froze for a moment.

Then he lowered his head and looked at the utterly ordinary delivery box tucked against his waist with his left hand.

The three large characters "[Invitation]" on it were exceptionally conspicuous.
