Yakuza Dead SoulsEdit
"Sweet death..." Hayashi upon reanimation.
A lone, mysterious figure in drab clothing crosses the paths of Shun Akiyama and Hana of Sky Finance, using a low-hanging baseball cap to conceal his identity. On a mission, the mystery man descends down the stairs towards the entrance of a building inhabited by members of a family under the Tojo clan. As he calls for the underground elevator, he is soon approached from behind by an unnamed Yakuza who enquires about his intentions for being there. Silent, the figure turns and suddenly bites the Yakuza's neck, killing him. The family members residing on the top floor witness the attack through a security camera feed and draw their weapons while the elevator approaches from below. The elevator opens, prompting the Yakuza to empty their guns into the lanky and sickly looking figure. Despite multiple gunshot wounds all over his body (including a bullet to the head), the man remains standing, looking towards them to reveal his red glowing eyes. The family are slaughtered and thusly reanimated as zombies, before taking to the streets of Kamurocho to wreak havok and begin to spread their newfound infection.
It is later revealed in Part 3 that the attacker is none other than Hiroshi Hayashi of the Omi Alliance.
Hayashi appears in the lift again as Ryuji warned last Yakuza family. Once the lift opens,Hayashi disappears and they shocked,but Hayashi is wrpped up the top of lift where they didn't catch him.

Then Hayashi shows his face to Ryuji and tell him or himself. "Sweet...Death...."Then Hayashi tried to run away and Ryuji shots him and then Hayashi jumped breaking the wall.
