In order to go to the treasure chamber together with his friends, Yuno confronts Mars alongside Klaus, so that the injured Mimosa can heal herself. But they have a hard time harming Mars at all.
And finally, they have them 
fight one another to the death.
وفي النّهاية، يجعلونهم يقاتلون 
.بعضهم حتّى الموت
Und schlussendlich treten sie in einem Kampf
auf Leben und Tod gegeneinander an.
y al final los obligan
a matarse entre sí.
y al final los obligan
a matarse entre sí.
Et enfin, on les fait s’entretuer.
E infine li spingono a combattere fra di loro
all'ultimo sangue.
Por fim, fazem-nas
se enfrentar até a morte.
А в конце они бились 
друг с другом насмерть.
