Artist's commentary
GuP Kindergarten Returns! Story 369 - How to Spend a Rainy Day Part 10
I drew this in commemoration of the Shimada Style figurine. (and also the teachers since there were some who voiced "wanting to see them")
English:
Shimada-san also came in his school uniform.
Teachers also started wearing cosplay... Mika-chan also began to take an interest in cosplay.
