<Others> The assistant teacher, Toshima, has been ordered by the principal to monitor Maruyama. He is a heavy smoker. He sometimes experiences cute aggression. He will not make a move immediately in the story. His act of being a normal person is perfect. He is a bit clumsy in daily life, but his clumsiness never triggers at critical moments; conversely, he has good luck. He seems to have a lot of free time after school.✦ ✧ ✦ ✧ ✦ ✧ ✦ ✧ ✦ ✧ ✦ ✧ ✦ ✧ ✦ ✧
