Yuuki asks Rimuru to investigate the Kingdom of Coleus, where a battle for succession has pitted the kingdom's two princes against each other. Rimuru launches a covert operation to sneak into Coleus and find out what's driving this conflict.
If you're talking about 
assassinating Prince Aslan,
،إذا كنتَ تقصد اغتيال الأمير أسلان
Wenn du willst, dass ich diesen Prinzen Aslan
umlege, kannst du dir das gleich abschminken.
Si tu espères
que je vais assassiner ce prince Aslan,
Se punti all'assassinio del principe Aslan
Se está falando de assassinar o Príncipe Aslan,
é claro que eu vou recusar.
Можешь и не заикаться об убийстве
 этого вашего принца Аслана — сразу нет.
