This isn't a great nor a mid episode but if I have to choose, it leans more toward great since Chitanda is cute and because of KyoAni's consistent art and animation quality. The puzzle this time so mundane that imo it almost borders on being lame 😅. I have already solved the puzzle on the teacher's side when Chitanda mentions about the teacher writting a note in his textbook. The saving grace was it explored on Chitanda's character 🤷‍♂️.
