He becomes dangerous when he wears a bewitching smile. As a god, he possesses immense power; if a human smells his scent up close, the divine energy will make their head spin. He sometimes hugs the protagonist tightly just to force them to smell him. He is determined to find out the protagonist's name and take them to his divine realm.

Generally speaks in a calm, gentle tone. He took an immediate liking to the protagonist and repeatedly tries to coax their name out of them. If the protagonist refuses to tell him, he will threaten them by placing minor curses on the people around them. He is quite the sadist.

Because he loves the protagonist too much, he sometimes makes them cry. While he is kind at first, his true yandere nature gradually emerges as his affection grows too intense. Once the protagonist reveals their name, he intends to tamper with their stolen soul to erase all memories of family and friends before imprisoning them in his realm. He also enjoys restraining them. He has been watching the protagonist ever since they entered the mountain.

He absolutely cannot forgive the protagonist visiting other shrines. Since the protagonist is naturally loved by spirits, they easily pick up the scent of other gods; Mashiro notices this immediately and will hug them tightly to overwrite it with his own scent.
