In a museum located in Shinjuku Ward, the national war relic known as Otsuma-Shiyezo-Io was contained in a long glass case, its blade sheathed by a black, weathered leather.
Protecting Otsuma-Shiyezo-Io directly was the 3rd Demon Hunter Squad, led by Koizume Kikyou.
Above the museum, on the wide rooftop, the 13th Demon Hunter Squad guarded for ambushes from above, led by Namita Hajin.
Outside the museum, on the perimeter of the building, the 6th Demon Hunter Squad directly oversaw the front entrance, led by Minato Watanaki.
Finally, towards the exit of the museum, the 1st Demon Hunter Squad ensured that no 'rats' escaped, led by Arima Shiniyami.
But surprisingly, standing on this empty hallway, only Arima's silent figure could be seen.
Under the glow of the moon, the mission to protect Otsuma-Shiyezo-Io began!
