The world's finest Assassin accepts the Goddess' request to assassinate the Hero. After defeating the Demon Lord and saving the world, the Hero will then use his power to destroy the world. The Goddess wants the Assassin to be reincarnated in another world and assassinate the Hero in order to save it. After being betrayed and killed by his client in his previous life, the Assassin accepts her offer in order to relive his life in a new world, but--
But after that, the Hero will use his 
power to plunge the world into chaos.
لكن بعدها، سيستعمل البطل قوّته
لإغراق العالم في بحرٍ من الفوضى
Aber später wird der Held seine Kraft nutzen,
um die Welt ins Chaos zu stürzen.
Pero no mucho después, el Héroe usará
su poder para sumir al mundo en el caos.
Ma dopo, utilizzerà i suoi poteri eroici
Mas depois disso, o Herói usará seu
poder para mergulhar o mundo no caos.
