Iwamoto-senpai no Suisen

About Iwamoto-senpai no Suisen

Iwamoto is a middle school student attending a military academy who receives a direct assignment from his headmaster to investigate the town of Shikibe. His orders send him away from the academy grounds to observe a local event known as the Donji Festival and examine the strange rumors attached to it. At the center of the assignment is a figure known throughout Shikibe as the Shining Miko, whose reputation draws attention during the festivities. Because accounts surrounding this shrine maiden suggest something out of the ordinary, the headmaster wants a clear and reliable assessment of what is actually taking place in the town. Acting on his headmaster's instructions, Iwamoto must look closely at the Donji Festival and the circumstances surrounding the Shining Miko's appearance. Rather than taking local claims at face value, his task as a military academy student is to observe the proceedings firsthand and gather concrete answers. The core question driving his investigation is whether the Shining Miko is nothing more than a staged trick or a genuine phenomenon. Every detail of the festival in Shikibe becomes a potential clue as he weighs ordinary deception against the possibility of something real. Caught between institutional duty and an unfamiliar local tradition, Iwamoto steps into the festivities of Shikibe with a focused objective. He must sort illusion from truth and fulfill his headmaster's mandate by determining the true nature of the town's Shining Miko.
