Dead Souls 2

=== Part I - Shun Akiyama ===
Finally putting the finishing touches on the Sotenbori branch of Sky Finance, Shun Akiyama and his secretary Hana - who insisted on helping him after her boss slacked off on the project for multiple years - when their office is suddenly rocked by a massive earthquake, sending files everywhere. Hana, complaining about the mess, begins cleaning up before the two hear an explosion out the window. When Akiyama runs to the window he sees Sotenbori on fire, and he forces Hana to evacuate.
As the two run away from their office, they are quickly swarmed by member of the Omi Alliance, who, panicked, attack the two. Though Akiyama tells Hana to run, she is trapped by the group of yakuza and is forced to fight alongside him. As the two defeat the goons, they remark that they're "just as annoying as They are" and flee, cursing Akiyama and Hana out in the process. Confused, Akiyama tries to ask the yakuza what they mean, but as flames engulf the building next to them he and Hana instead run for cover. As they are pushed by crowds of people, the two duck into the Cabaret Grand down the street to try and get out of the herd. As they try to enter the building, they hear pounding coming from the inside, and Akiyama enters to find the building filled with zombies. Scared and confused, he tells Hana to run, and the zombies flood out of the cabaret after them. Wanting to protect the people nearby, who see the new threat and begin to panic even further, Akiyama and Hana decide to fight the hoard as they slowly exist the building.
After clearing the building out, the two realize that, sometime during the fight, the street became eerily quiet. Worried that more of those zombies could be present in the city, Hana suggests the two should escape back to Kamurocho, to safety. Unfortunately, as they try to leave the city, they find that Omi Alliance has circled the city, preventing anyone from escaping. As Hana and Akiyama are pushed back into the city, the former catches sight of someone whom he believed had been incarcerated after the events a year prior: Kamon Kanai. Kanai does not notice Akiyama, but the latter realizes that his appearance in the city must mean something it going down and that he needs to investigate. However, now that his office has gone up in flames, Akiyama decides to head to a building that he has allies in: the Dyna Chair production office, where Haruka Sawamura worked a year ago.
Reaching Dyna Chair, Akiyama and Hana are quickly welcomed in by Misa Yamaura and Hiroshi Horie, who remember the former from his time with them previously. The two of them, as well as the legendary dance instructor Christina, are boarding up the windows and the door, though allow the two to enter regardless. Knowing that something is amiss, Akiyama questions the three about what they know, though they just reveal that "monsters" and the sudden influx of yakuza are harassing any establishment still open in the area, so the three decided to go into lockdown. The group is then surprised when their former idols, Azusa Osawa and Misa Yamaura, appear at the door in a panic. The two reveal that the yakuza broke into Osaka Talent and began to indiscriminately murder anyone they found, so they escaped and came to their former place of work. Akiyama, especially confused about what is happening in Sotenbori, leaves Hana at Dyna Chair and requests that the group shelter anyone who requires help, to which they agree. He leaves the building and is immediately confronted by a hoard of zombies barrelling down the street towards the office, so he begins to flee the other way. He is surprised when, suddenly from behind him, his former trainer Daijiro Saigo appears with a plethora of guns at his disposal, and hands one to Akiyama telling him that running away isn't what a true soldier does. Though annoyed, Akiyama accepts a pistol from Saigo and the two begin working together to cut down the zombies.
