him, and Amamiya has to turn to another student for protection. Kijima, the "protector," has his own motives. Amamiya then decides to play the doting teacher, and encourages Mifune's affection
while eliciting a warning from Kijima: Stay away from Mifune, or else. What Amamiya does not realize is that sheepish Mifune's wolf persona is about to reverse his luck in love.
