Sousuke Minamino is the devoted husband of Misora Minamino and father to Kanade and Souta Minamino. As owner and head patissier of their family-run cake shop, Lucky Spoon in Kanon Town, his culinary passion centers on crafting cupcakes and confections designed to spark joy through every sweet creation. This heartfelt dedication directly inspires his daughter Kanade's own dream of becoming a pastry chef.

He shares an openly affectionate bond with Misora, their frequent displays of mutual adoration prompting lighthearted reactions from Kanade. An enthusiastic and occasionally overprotective parent, Sousuke reacts with intense emotion when sensing threats to his family—exemplified when he tearfully clutched Kanade after an unexpected encounter with Mephisto in her room.

At Lucky Spoon, Sousuke spearheads constant recipe innovation with his family's support, viewing desserts as vessels of happiness that blend technical skill with emotional warmth. This philosophy shapes both the shop's operations and household dynamics, continuously reinforcing Kanade's patisserie ambitions.
