   [Ongoing] This is a fanfiction about Diamond A, labeled as pure love, but I haven't figured out who the pairing is yet, so please treat it as a no-pairing story. Miyuki is in the same grade, childhood friends from the "bad buddies" group, and a pitcher who became an ace in his second year. They were part of the Higashi-Kiyoku generation to reach Koshien. One thing I really like about this story is that although he's a pitcher, he treats Tanba and other Seido pitchers more like teammates than opponents, offering encouragement and help. He doesn't have any strange possessiveness towards Miyuki (it might just be the leeway of childhood friendship; anyway, it's a very comfortable story).

So he treasures this friendship, which took a long time to grow and was hard-won. Until one day, their friendship turned into something else. But luckily, the other person's friendship had its share of impurities, too. We grew up in an imperfect summer and met in the quiet. To you, ordinary yet dazzling, To you, small yet extraordinary, To you, whom I love, To our irreplaceable youth, shining forever. It's probably a classic story about how we may seem 116Favorites163Clicks/ch200Gifts

   [Serialized] A fanfiction about Diamond A, with Miyuki as the main character. It can be viewed as a school romance novel. A transfer student from China is dating the catcher of a top baseball team... Why aren't they dating yet (laughs)? It's about a strong girl's journey of studying abroad. Studying abroad sounds really tough. Communicating entirely in a broken foreign language is already a nightmare, but you also have to socialize, attend classes, and so on. Anyone who isn't independent and strong enough couldn't handle it. Respect!

   [Serialized] A fanfiction about Diamond A, pairing with Kazuya Miyuki. Throughout the story, everyone has a one-sided crush on the female lead. Joe Cheng (from Haikyuu!!), Prince of Tennis, and Hyouka are just background characters. This kind of universally adored setting feels surprisingly normal in the writing. The female lead is practically a goddess of baseball and victory, a straightforward, rich girl who loves baseball more than anyone else. Which baseball guy can resist Chitanda's charm? I certainly can't. Although there aren't many matches, a youthful school romance comedy should focus on everyday life, and it's very enjoyable.

That was the year he was recruited by Seido High, beginning the legendary baseball career that lay ahead of him.

   [Updated 2026] Diamond Ace fanfic, no romance. The author, relying on their solid baseball knowledge, changed everything that could be changed, yet it all makes sense, and they even educate us newbies. The characters are very faithful to the original work—amazing! This reminds me of the Harry Potter: The Way of Reason that I used to cram into; it's a complete showcase of skill. It's just that it hasn't been updated in over three months, so I'm almost embarrassed to label it as ongoing…

   [Ongoing] A BL (Boys' Love) fanfic featuring Diamond A, a crossover of "Forget the Merits and Demerits of Pitcher and Catcher," with Miyuki Kazuya as the main character. He's a pitcher. He's good at writing about matches, but his romance is so-so. To be honest, it feels like the relationship hasn't reached that point yet—the confession, the getting together, and the telling of the coach all happened before. He should write more about matches.

   [Ongoing] A-rank A-level fanfic, no romance. He's in the same class as Miyuki, a pitcher. This is a genuine youth sports psychological suspense story. The protagonist's thought process is a bit strange; currently, they're still communicating in a lot of ways. His interactions with Miyuki are very childish, which is quite interesting.

    [Unfinished] A BL fanfiction featuring the protagonist, Kazuya Miyuki. Sawamura is the main character, and the story revolves around him. The author is bold in depicting the protagonist's struggles and subsequent rise, resulting in very noticeable character development. While the early plot is somewhat strange and has a dated feel, the author improves rapidly, getting better with each chapter. The story is only in its second year. Unfortunately, another author plagiarized this work and has stopped updating, so this one is likely truly unfinished.

    [Completed] A BL (Boys' Love) fanfiction featuring Miyuki and Sawamura. Sweet, sweet, sweet, with a soul-swap trope. It's rather unusual that Sawamura manages to lead his Nagano friends to victory in a competition, becoming the hero captain of a defunct school and living a legendary middle school life. Also rather unusual, Sawamura helps Miyuki grow a mouth, resulting in Miyuki becoming someone skilled at making friends (?). (Although it's still marked as a serialized story, I think it can be read as a completed work.)
