Deaimon: Recipe for Happiness

Kanoko followed Nagomu to Kyoto, but back when they parted ways, she'd been stubborn and said, "I like Western sweets better." Faced with that, she can't find a way to be upfront and cheer Nagomu on now. Meanwhile, Nagomu begins kicking up a fuss about losing his headgear from his band, Chestnut Manju. With Kanoko and Itsuka's help, Nagomu searches for it, but...

A new artisan, Kisaichi Hiiro, arrives at Ryokushou. Enchanted by artisan Tatsumi Masa's sculpted sweets, Hiiro decides to become a wagashi artisan herself. However, her overly serious mindset and perfectionism cause her to lose sight of her surroundings and to make mistakes. She becomes despondent, then Masa teaches her about the spirit of an artisan. Amidst all of this, due to a whim of Nagomu's, Ryokushou holds a "Hands-on Wagashi Class" at the elementary school Itsuka attends.

Everyone at Ryokushou is participating in the Miyama school district's sports festival. Itsuka feels shy and awkward around Nagomu, causing her to adopt a brusque manner toward him. But in his loud cheers of encouragement she feels the warmth of family. Nagomu's father, Heigo, gets overly fired up and ends up hurting himself. Nagomu and Itsuka have to step up to take his and Nagomu's place in the parent-child event. Meanwhile, at Ryokushou, a woman calling herself Itsuka's mother appears.

On a day off from work, Itsuka and Mitsuru run into Nagomu's ex-girlfriend, Matsukaze Kanoko, in town. Mitsuru and Kanoko haven't met before, though Itsuka knows them both. The three decide to have lunch together. Mitsuru and Kanoko both get excited talking about Nagomu while Itsuka is perplexed by the unusual atmosphere between the two women.

A regular customer cancels their order. Nagomu's father, Irino Heigo, is furious with him, thinking that Nagomu has done something again. Heigo and Nagomu go to apologize to their regular customer. There they find out that the cancellation was actually connected to someone else who works at Ryokushou, Seto Saki.

One morning, on her way to school, Itsuka spots someone who looks like her father getting on a bus. She gets on the same bus to see if it really is him, but ends up falling asleep. Having lost sight of the person who looks like her father, Itsuka arrives in Ohara near the Sanzen-in Temple where she happens upon someone unexpected.

Horikawa Mitsuru, a high school student, works at Ryokushou with Itsuka. Seeing the two of them chatting happily together by the sink makes Nagomu feel a little jealous. While Mitsuru works part-time at Rykoushou to help supplement her large family's finances, she's also actively making music. And her musical activities kick up some trouble.

In front of Kyoto Station, Yukihira Itsuka mistakes Irino Nagomu for her missing father. She never imagined that he was the son and heir(?) to a wagashi shop called Ryokushou—the same shop where she's been staying. When Nagomu and Itsuka begin working together at Ryokushou, they run into a little trouble.
