It has been twenty years since the tragedy of Bugs 2 and is now 2619. In order to save his childhood friend, Yuriko, from an unknown illness, Hizamaru Akari was fighting in an underground arena in Bangkok.
Ever since that day.
‫منذ ذلك اليوم
Seit diesem einen Tag …
Desde aquel día...
Desde aquel día...
Depuis ce jour-là,
Da quel giorno, io...
Desde aquele dia.
