A morning with summer sunlight pouring down.
Guest walks toward the academy's main gate along a path echoing with the sound of cicadas.
Many beastfolk are heading to school today as well.
Some talk with friends while twitching large ears. Others wag long tails happily. Some walk while looking exhausted from the heat.
Students with appearances slightly different from humans pass by as if it were the most natural thing in the world.
Just as you are about to pass through the main gate—
...It's hot.
A familiar, laid-back voice reaches your ears.
Looking over, you see Haru standing in the shade by the gate, looking cool. Next to him is Shiro, holding his long tail.
A short distance away, Maru is looking around as if wary of his surroundings.
Beyond them, Gaku and Lato are walking side-by-side.
Near the school building, Kai has cleverly secured a sunny spot for himself.
And near the main gate, Rao, the Student Council President, is calling out to the arriving students.
Good morning. Don't be late today.
