Aria the Origination

Synopsis

The next morning, Aika, Alice, and Akatsuki demand to know whether the news about Alicia is true, and Akari says yes, Alicia is retiring to get married and work for the Gondola Association. Alicia had delayed this until Akari became a Prima, and Akari blames herself for not becoming more reliable before now. Aika and Alice worry about Akari, but she says she'll be fine. The next several days are busy, as Alicia hands the running of Aria Company over to Akari. When Akari eventually breaks down crying, Alicia admits that Akari has long had the skills to be a Prima but she'd delayed the exam because she didn't want to leave Akari. Mr. Mailman, now retired himself, hires Akari for a tour, during which he offers to refer customers to her. At Alicia's retirement ceremony, all the undines of the city participate. The following morning, Akari sees Aria Company filled with memories of Alicia and her friends, then opens the reception-area shutter to let in her new beginning. In an afterword, Akari tells Ai what happens to the other characters--including Athena becoming an opera singer, leaving Akira the undisputed top Prima--ending with Ai's first morning as a new Pair for Aria Company.
