Ace of Diamond: I’m the Secret Weapon at Seido

This is so good! Author, please keep updating! There are so few stories by A-list authors, so please don't stop updating. Keep it up! Also, the interactions between A-He and Miyuki, though few, have a unique feel to them, which is great. The interactions between the brothers are so sweet! 💕💕💕

I really love the protagonist's personality and his interactions with Eijun and Miyuki. I hope there will be more updates.

It's a great show; the interactions between the cool, brother-obsessed older brother and the hot-blooded, goofy younger brother are very interesting.

Wow, look what I found! Diamond Fan Art! Waaaaah, it's so well written!

This is a rare gem of a story by Tomato, perfectly capturing the personalities of the original characters. The emotional descriptions are delicate, and some of the action scenes are incredibly satisfying 😋. It doesn't overshadow the original but rather adds its own highlights. When I saw that the character is Eijun's older brother, I was worried that Eijun would be made too powerful.

The characters haven't deviated from their established personas, and I really like the pairing, so I'll continue updating 😢

This book is incredibly well-written, unlike other stories that stifle the growth potential of other characters. Ahhh, maybe it's because I love it, but the author portrays every character so likable. It's just a shame I only discovered this book in 2026! Even though it's unfinished, it's still a very, very enjoyable Diamond/Ace series.

The romance is so delicate and develops so naturally. The original male lead's character design and personality are also logical; only a male lead like him could spark a connection with Miyuki. I think the catcher, rather than the pitcher, would understand and connect with Miyuki better!

It's really good! Author, please continue writing this book; there's still hope for the author! 😢

I became obsessed with Diamond A at the beginning of the year and have been searching for doujinshi ever since. It was only through a recommendation on Lofter that I discovered this absolutely amazing story. I feel like Diamond A is a bit niche; there aren't many well-written doujinshi. Most are either abandoned, short stories with only one or two chapters, or just haphazardly written.
