Hazuki Family's maid Ine hands a letter to Ryo, who is restless from his Father's death. The letter was sent from a person named "Yuanda Zhu" to his father which contained characters he cannot read. Ryo begins investigating the letter to find out his Father's past. As he further investigates, he is targeted by "Mad Angels", the gang that runs Yokosuka Harbor's underground business.
Isn't he out there digging 
up his father's past
ألم يخرج للبحث في ماضي والده ليكتشف ما أدّى لمقتله؟
Versucht er nicht die Wahrheit
über den Mord zu erfahren,
Investiga el pasado de su padre
Está investigando el pasado de su padre
En fouillant le passé d’Iwao,
Non è che sta indagando sul passato di Iwao
per capire le cause del suo omicidio?
Ele não está desenterrando o passado de 
seu pai para determinar o que levou à sua morte?
Он ведь раскапывает прошлое Ивао
