Viper's Creed: Season 1, Episode 8
Theresia Strauss, AGS official, suggests to Fuyuhiko Oguma that Haruki was the most likely culprit for yesterday's failed mission. Doubt begins to surface from within the Blademen unit when Norma suggests that a double agent was responsible for their recent anti-Hounds operation. Haruki encounters Ulla, but is seen speaking with Theresia in an abandoned church. He later returns to AGS headquarters and finds a hidden garden of flowers created by his father to honor his late mother. Haruki was assassinated in the building after his encounter with Ulla with Kariya and Saiki being the only witnesses to his death.
