Synopsis

After reading a certain baseball manga, Matsuda Mashiro fell for one of its characters.

To understand her fave better, she did her best to ask Miyuki Kazuya, a guy she barely knew, to teach her about baseball.

Then, as they slowly grew closer, she realized...

How is Miyuki so much like her fave?! The more she looks, the more alike they are! Is that even possible?!

Matsuda Mashiro never meant to use him as a substitute for her fictional fave, but after rounding things up, that's exactly what she seems to be doing. Her mind is blown.

Miyuki Kazuya has recently fallen for a girl.

She's great in every way, except for her terrible taste.

Whenever she praises that character she likes, he thinks, What's so great about him?

She'd be better off liking me.

[Reader's Guide]

1. This is my interpretation of the characters.

2. It's more or less a story about finding a real-life substitute for a fictional character (?).

3. Probably a short story.

My 2026 Fully Purchased Reading List

Finished reading this year, though not necessarily completed this year. Ongoing list. P.S. If I finished it, that means it was already really good. If it’s not on the list, I either haven’t read it, hit a landmine, or found it boring.

Baseball Fanfiction

Completed stories, ongoing stories, irregularly updated stories, and abandoned ones I've read that are pretty good. Mostly about Diamond no Ace, with a little Battery and some original fiction.

Two Words

Fanworks I love. They may not suit people with lots of dealbreakers (yeah, I'm pretty eclectic). Some got four stars by force because the site won't accept all five stars, even though I genuinely love them all.

Ace of Diamond / Forgetful Eight / Big Windup! / Baseball

Some baseball fanfiction I personally like, plus a few original baseball stories. Some recommendations cover two different periods, so there may be duplicates.

Baseball Fanfiction Recommendations: Ace of Diamond, The Prince of Tennis

Most of these are Diamond no Ace fanfiction, both BG and BL. Pick whichever you like. I don’t want a mixed-sports-anime reading list, so I’m planning to split it into several lists of my own.

Sports Anime Fanfiction Recommendations

Haikyuu, Prince of Tennis, Kuroko's Basketball, and soccer: Japanese school sports anime. I only read fluffy sweet stories. Five stars means I've reread it several times; four stars means I'd read it again when I'm in a slump.
