Reo Turns into a Little Kid During Their Cold War?!

This novel contains two complete short stories, featuring age regression, the King Game, and a brief gender swap for the uke. The writing is solid. Thanks for reading!

Short Story 1:

* Timeline: Post-U20, during their vacation and cold war

* Nagi's obsessive fixation became so intense that Reo accidentally shrank. The two were bound together by a physical chain and forced to spend their vacation together.

* From seven to fifteen to seventeen years old, on some level, Nagi got to experience raising Reo.

* Includes a King Game scene.

[Excerpt]

Yukimiya asked with a smile, “Then, does number three still have their first kiss?”

“Who is number th, ”

“Oh, I don't.” To everyone's surprise, Nagi raised his number three card and answered nonchalantly.

Short Story 2:

* During the second selection

* Reo, who wasn't chosen by Nagi, sank into despair. Chigiri and Kunigami invited him to join them, but then he suddenly turned into a girl?!

[Excerpt]

Reo couldn't believe the voice he'd just heard had come from him either. Maybe it was because he'd just been crying. He cleared his throat and tried again. “Is something wrong?”

As soon as he spoke, not only Reo and Kunigami, but Chigiri as well, froze. They hadn't interacted much before, but had Mikage Reo's voice always been so... androgynous?

His voice now had neither the rich, low timbre of an adult man nor the clear, bright tone of a boy. Instead, it was close to a mature woman's voice, airy yet husky and resonant.

Theme: Let's become the world's number one strikers together!
