1x2 - Aria the Scarlet Ammo

Aria demands that Kinji join her Butei party, intruding in his living space when he refuses. This puts Kinji in an awkward situation when his childhood friend, Shirayuki Hotogi, pops over whilst Aria is taking a bath. The next day, Aria follows Kinji around as he takes on a quest to search for a missing cat. After managing to lose Aria, Kinji trades some eroges with his friend, Riko Mine, to obtain information on Aria. Meanwhile, Aria calls Kinji's bluff on his Butei abilities and coerces him to agree to join her on a single Assault case, so she can witness his Hysteria Mode.
