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--
Saving the world without killing 
the Hero would be great, too...
سيكون إنقاذ العالم دون قتل البطل رائعاً
Wäre wirklich schön, wenn das gelingt,
ohne den Helden zu töten.
Y sería estupendo que salvaras el mundo
sin tener que matar el Héroe,
Y sería estupendo que salvaras
el mundo sin tener que matar al Héroe,
Si c’est faisable sans tuer le héros,
pourquoi pas ?
Se è possibile senza uccidere l'eroe,
va più che bene.
E não seria ruim salvar o
mundo sem matar o Herói.
Будет прекрасно, если мир удастся 
спасти без убийства героя.
