Tsuihousha Shokudou e Youkoso!: Saikyou Party wo Tsuihousareta Ryourinin (Lv. 99) wa, Inaka de Nengan no Boukensha Shokudou wo Hirakimasu!

Dennis, a top-tier cook, is cast out by the Silver Wings Battalion after being betrayed by those he trusted. Rather than dwell on the loss, he uses his level 99 cooking abilities to open a diner in the countryside. There, he meets Atrielle, a girl who was exiled from her noble family and forced into servitude, whom he rescues and helps establish the restaurant. Their first customer is a knight also exiled from her guild, followed by a confident mage and a hardworking but poorly compensated sage who become regulars. The knight occasionally causes problems, but Dennis uses his culinary talents and knives to manage both the chaos and the meals. The diner and its reputation begin to grow in the local community.
