Summary
"STOP HER FROM RUNNING!" someone shouted in the distance.
His heart pounded a thousand miles a minute as he dodged another tree branch to the face. He might have lost a shoe along the way, but who cared about a stupid shoe when an army of royal guards was chasing him?
All he'd done was try to help Wakana. How the hell had he ended up being chased by the stupidly—and he loathed to admit it—handsome crown prince of Seido?
And damn it if this ridiculous dress wasn't making running even harder.Series

Summary
As the song comes to a close, everyone in the crowd is cheering loud. Sawamura soaks it all up, smile stretching as wide as it can get. Unlike last time, the band doesn’t introduce themselves. They go right into playing another song. Wakana starts off singing this song, but Kazuya can’t take his eyes off of Sawamura. He was being stupid thinking his feelings were just from playing baseball with Sawamura. No, Kazuya fell in love with Sawamura’s personality, his energy, his determination. Baseball may have introduced him to all of that, but Kazuya fell in love with Sawamura for everything that he is. Kazuya was in love with Sawamura the pitcher, he is in love with Sawamura the rockstar, and he would still be in love with Sawamura if he became something else. Kazuya is pretty sure he’ll never love someone the way he loves Sawamura Eijun.
– –
Sawamura reenters Kazuya's life in a way he least expected, and now he must deal with unresolved feelings, longing, and his fears.

Summary
Haruka was silent. Which wasn’t unusual, except… he wasn’t just quiet. He was staring.
Trying to figure out why Kei was smiling like that at someone else. Smiling that bright, easy smile that—until now—Haruka had thought was only for him
“Haruka’s our pitcher!” Kei continued cheerfully, oblivious to the way his pitcher’s expression darkened like a storm cloud. “He’s really amazing! He throws so fast and his control is perfect and he never talks to anyone but talks to me sometimes and—”
“Really?!” Sawamura lit up, which should’ve been physically impossible considering how bright he already was. “That’s so cool! I’m a pitcher too! We should totally have a pitching contest later! I bet your pitcher is really good, but I’m pretty good too and—”
“That sounds fun!” Kei exclaimed.
Haruka’s eye twitched.

Summary
Since graduation from Seido, life had taken everyone to separate paths. But one thing remained -- baseball continue to be a common language among the team. No matter how far they will go in life, they will always find each other in the baseball diamond...
Miyuki didn't seem alarmed, and yawned exaggerately, "Cinderella, it's time to go home."
Instead of taking that as a cue to leave, Kuramochi planted himself next to Miyuki on the couch, and turned off the TV, "Miyuki, what's going on."His voice carried an unweavering tone, but Miyuki didn't seem to be bothered, and just grinned back, "It's getting late."
Kuramochi sighed and took out his phone. He flipped through pages of social media, as he spoke, "Miyuki, what are you doing here? It's league championships right now, you don't seem to be injured, what could bring a superstar catcher all the way here?" Before Miyuki could speak up, Kuramochi looked up at him sharply, "And don't tell me you're here to deliver the present."
Miyuki dropped his chin, and rested it on the cushion in front of him. He spoke as he blinked innocently, "I didn't know I needed a reason to visit friends." -

Summary
Miyuki ignores the pitchers one too many times, so Sawamura takes him to court. No one actually knows what's going on.

Summary
You didn’t come to Seidou to be noticed. You’re not a player, not a prodigy. You’re just the team’s new manager—someone who loves baseball enough to stay behind the scenes, filling water bottles, tracking stats, and making sure everyone’s ready for the next big game. Miyuki teases you like it’s a sport of its own. Kuramochi drags you into chaos more often than not. But it’s Takigawa Chris Yuu who quietly pulls your attention. He doesn’t say much. Always focused, always a little distant. Yet there’s something steady in him. Something that makes you look twice, then keep looking.

Summary
“What if Sawamura Eijun had the right coach—and found baseball a little earlier?”
Raised in the heart of Los Angeles by Japanese parents, Eijun grows up surrounded by cultures, chaos, and the occasional late-night baseball game on TV. One afternoon, his boundless energy leads him to a neighborhood park—and to the sport that will change everything.
With the right guidance, talent sharpens. Passion deepens. From dusty sandlots in LA to youth leagues and state tournaments, Eijun learns what it means to pitch—not just loud, but smart. Years later, when he moves back to Japan, a new challenge awaits: Seidou High, a school known for turning raw talent into legends.
A Daiya no Ace AU where Eijun starts young, trains hard, and walks into Seidou not as a wild card—but as a true contender.

Summary
Moving from rural Akita to Tokyo was not easy. Attending a big high school like Seidou when all of the schooling experience you have comes from an small all-girls school was not easy. Having to meet and befriend the baseball team because your only friends are the managers of said team was not easy- at first.
All of these things would be a lot easier if that short guy with pink hair would just stop looking at you like that.
(Reader meets the baseball club and is instantly scared of Ryousuke. Somewhere along the way, though, they fall in love).

Summary
When Sawamura woke, he wasn’t in a cage.
He was lying on a cot in a sunlit room that smelled like dried herbs and leather polish. Bandages wrapped his ribs. The suppression collar was gone. His wings, though still sore and heavy, had been cleaned and splinted.
And sitting across the room, sharpening a dagger like it was the most natural thing in the world, was the same wolf hybrid who’d pulled him out.
“Morning, Flightless,” the man said without looking up.
Sawamura growled.
“I can fly,” he snapped.
“Sure you can,” the wolf said mildly. “Name’s Miyuki. You’re at Seidou now. You try to escape, I’ll catch you. You try to fight, I’ll knock you flat. You want to live, you listen.”
Sawamura bared his teeth.
But something in his chest—the part that had been curled up and screaming for years—finally exhaled.
Maybe…
Maybe he wasn’t alone anymore. -
