30-sai de "Seibetsu ga, Nai!" to Hanmei shita Ore ga Around Fifty ni Natte Wakatta Koto.

Following his 30th birthday, manga artist Shou Arai has been troubled by an existential question with no definitive answer: how does a person with no gender age? Since discovering that he was intersex 20 years ago, Shou has found very little information about individuals like him and what it means to grow up as a gender and sexual minority. But he is not the only one experiencing identity-related confusion, as his loyal readers and fellow manga artist colleagues are equally baffled and curious. While he goes through this mid-life crisis, Shou comprehensively documents the things he learns about aging and gender expression in hopes of answering all of these questions and helping those who are in similar situations.
