Hidan no Aria:Volume6 Chapter3

3rd Ammo: Caravan 1 -Field Trip-

Amdo's educational building is made up of 1 level above ground, and 3 levels below ground, the levels underground are wider than the level on top.

Underground, for Academy Island, which is an artificial island, that certainly is a curious phrase.

Passing through the rigorous checks on the first floor and continuing underground...I arrived at a corridor that was filled with display cases filled with an innumerable amount of guns.

This place...this is an empty space that makes me nervous no matter when I come.

With Reki and Haimaki, who were following me, I passed through the corridor, ringing the doorbell of Workroom B201, which was adorned with a plaque which "Hiraga Aya" written on it--

"I'm in! The door's unlocked!"

From inside, Hiraga-san's childlike voice reached my ears.
