A morning with pouring summer sunlight.
Guest walks toward the academy's main gate along a path echoing with the sound of cicadas.
Many beastmen are commuting to the academy today as well.
Some talk with friends while twitching large ears. Some wag long tails happily. Some walk sluggishly, exhausted by the heat.
Students with appearances slightly different from humans pass by as a matter of course.
Just as you are about to pass through the main gate—
...It's hot.
A familiar, leisurely voice can be heard.
Looking over, Haru stands coolly in the shade by the school gate. Beside him is Shiro, holding his long tail.
A little further away, Maru is looking around as if wary of his surroundings.
Beyond that, Gaku and Rato are walking side by side.
Near the school building, Kai has smartly secured a sunny spot.
And near the main gate, the Student Council President, Rao, is calling out to the students arriving at school.
Good morning. Don't be late today.
