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.)

Okay, get this - Sawamura Eirin, but a year younger than her brother. Going through high school with a very over protective brother who practically forced her to play baseball when they were younger but now, she loves it. Follow her on her journey of living in Tokyo, watching her brother play baseball and missing her best friend from back home. This is just another version of Sawamura Eirin from Baseball Genius and I just couldn't get the idea out of my head.

Alex Hernandez thought her life was perfect she is a sophomore and has lived in Los Angeles California, and plays baseball for high school team after getting to prove herself capable of playing a "Boys" game but all that changes after she gets home from practice. Her father gets transferred to Japan for his company for years, and they all must go as well. She has to say good bye to her teammates, her best friends and her crush. What worse is that when she gets their she finds out that she will be attending Seidou high a baseball school. Where she meets a very sarcastic and twisted catcher that somehow weasels his way into her life. Along the way she will make new friends and have a new team, but will she be able to go back home when the time ends to the best baseball teams or will she stay for the guy she fell in love with? I did not create any characters from Diamond no Ace those characters belong to the author of the manga Yuji Terajima. The characters that do not appear in DNA are were created by me.

Precision pitch control, an aggressive playing style, and the mental fortitude to match. Stamina for days, adaptable and reliable batting skills, and natural leadership abilities. "Too bad all of that talent is wasted on a girl. You'll never make it pro." And the stubbornness to prove them wrong. Add in a dash of sailor's mouth and enough spite to fuel an army and you've got yourself an explosive mixture. Narumiya Alexia has just moved back to Tokyo from America and after joining a local powerhouse school, she's looking to prove herself on the field. And to settle an old grudge.

This is a Haikyuu x Diamond no Ace crossover, but focusing on the Diamond no Ace. A girl who has Tōru as her older brother, but just by the title. A girl who dreamt of going to Inashiro so she could go to Koshien. A girl who wanted to catch for a certain boy named Narumiya Mei. And a girl who had to find out that everything could not always go to her liking. Highest rank #1
