Yuji Sawamura is a young man who is lively, caustic, and serious. Despite having a difficult upbringing, the man is focused on more important pursuits, like baseball. After receiving an invitation for the Sawamura twins both to play baseball in Tokyo at Seidou, Yuji made the decision to accompany his brother. How Yuji will develop as a person and batter, and whether he will be given the nickname "The Demon hitter"? I don't own any character besides Yuj. Slow updates

Haruka Inejiro was messed up in every way imaginable. However, despite his heavy anxiety issues and explosive temperament, he never stopped loving baseball. In the same way, baseball loved right him back. [diamond no ace] [miyuki kazuya x male!oc]

He's a self-assured, attractive and talented catcher. She's a sassy, determined transfer student who is nothing like any girl he has met before. Miyuki Kazuya will learn that not everything can be solved by analysing the details, and that life can sometimes throw you a curveball that can change you in ways you couldn't imagine. [Miyuki Kazuya x OC] This is my take on the high school life of the Seido baseball team. It focuses around Miyuki, Kuramochi, Ryosuke and an original character, with some cameos from other favourite characters along the way. The story is inspired by the series, with my creative license used to explore and develop the characters outside of baseball. Enjoy! **Diamond no Ace characters and story belong to Terajima Yuji. I only own the OC contained in this story**

Sawamura recently learns that Ryousuke, Haruichi's brother, and Tatsune, Yuuki Tetsuya's younger sister, are dating. Curious as to how the love between two unexpected people blossomed, Sawamura asked his upperclassmen. Looking back on the events that led to this iconic couple, the Seidou Baseball Team regulars tell the story of how the pink haired second baseman and their captain's little sister became a couple. Daiya no Ace belongs to Terajima Yuji. I do not own any characters other than my OC.

Sawamura Eirin is Sawamura Eijun's younger twin sister. She once was an amazing baseball player, extremely outgoing but after an incident left her arm shattered, she left the baseball field in fear. Eijun gets scouted for Seidou, and there is a chance for her arm to be fully healed. Eirin goes with her brother to Tokyo. With the help of new friends, is it possible she will go back on the field of her favorite sport? (This is also posted by me on a website called Quotev. I only own Sawamura Eirin and the Nagano Sharks.)

What if after the last game of Akagi Junior High, Eijun threw himself into learning more about baseball. What if he acknowledges that he isn't that smart, and knows that his only chance is to be recruited for a big baseball high school? would he show up to Seidou differently than in cannon? How would people react? Disclaimer: This is a Ace of Diamond fanfiction :) Also, I included any links to written sources at the end of each chapter... the cover art isn't mine. I will let y'all know if any of the art is mine :p *Now cross posted on AO3 under my alt pseudonym Maeribella_Haber

What happens if Eijun Sawamura had a twin sister? Meet fifteen year old Hikaru Sawamura, ace batter and right fielder for Akagi Junior High School. There is just one small problem....Hikaru is always mistaken for a boy, but she is a girl. However, when Rei Takashima comes and offers her brother a scholarship and by some weird turn of events MR. Hikaru Sawamura gets a scholarship...what will happen if Hikaru goes to Seidou disguised as a boy? Will her batting or right fielding stay top notch or will she fall? Will Hikaru be found out? Amazing cover done by iAMaSTARKIDranger (Thanks)

The story of Furuya Satoru and his twin sister, Satomi. Furuya has always been a little introverted, but his sister is his opposite. She is outgoing and sarcastic, and a devil of a baseball manager (at least, according to Furuya's Junior high team). How will these characters adapt to Seido? Who should be more afraid: Seido or the baseball club? (Ace of Diamond FanFiction, I do not own any of the characters except Satomi and any original characters).
