As for the character design of keeper, I want a serious but cute little old man. In the animation, he is a serious parent type who maintains the overall environment of the bell tower, including the flowers and plants. In order to keep the bell tower and the flowers and plants clean, he would clear away the superfluous and wantonly growing flowers and plants. But he was reluctant to use force to solve the problem unless he had to. So I designed the very thick eyebrows and beards to cover his eyes and mouth, in order to create a solemn old grandfather.
