Sui helping Mukouda make food. 100/100 adorable!
I hope that this becomes an anime and use real Japanese products for promotional purposes. "It's thanks to this XXXX brand of salad dressing from XXXX foods inc! Delicious!"
Mukouda suddenly being proactive with requests, well... He is now an adventurer after all, he has responsibilities to answer to the guild because he reaps the benefits of being a member too (dismantling, selling of loot, etc) And unlike when he was running away from the first kingdom, he is not alone anymore and his companions are more than eager to protect him (food source). If anything seems fishy, Fer is a wise beast, Mukouda can have a conversation with him and ask for his opinion, he will need his approval too.
Even if he doesn't accept the guild requests, Fer will go out to slaughter that lizard and those bloody hornbull for game regardless, so why not just accept the request, make it official and get both meat AND guild reward + promotion at the same time? Not accepting it after Fer expressed his interest will be a loss, the guild will still have the job done for less pay.
The country using Mukouda? When Fer can destroy a country overnight? If they have brains they wouldn't dare. 😱
