"Have you heard? Seidou's got a witch coaching them now!" "Hah?! A witch?!" "That's wrong. That woman can't even be compared to a witch... she's the devil." (Slight!One Outs and Eyeshield 21 crossover) Reminder: This is a fanfiction I only own my OC and not any characters or content from One Outs, Eyeshield 21, or Diamond no Ace

Kobayashi Emi is Karasuno's third manager, however, due to her parents job, she had to move all the way from Miyagi to Tokyo. Emi then embarks on a journey of being a basebal managers and meets Miyuki Kazuya, the famous cocky catcher, and where she makes new friendships. The story begins on Haikyuu's second season up to Karasuno's Summer Camp and during the Baseball Summer Tournament. Also, the timeline in Haikyuu and Ace of the Diamond are slightly different to each other, especially the dates in the calendar, so I might alterate Haikyuu's calendar and make it fit with Ace of the Diamond calendar. Sorry, I suck at descriptions. Hopefully you give this story a chance. This story was honestly inspired by a fanfic called "Another Manager" by LoveAi2 on Wattpad, if you have any interest, go check it out! HaikyuuxAceofDiamond crossover. I do not own any of the plot, characters, nor translations. "Haikyuu!!" plot and characters belong to Haruichi Furudate-san. "Ace of Diamond" plot and characters belong to Yuji Terajima-san. I only own my OC character. The plot is much like the anime, meaning that I am not changing much the original plot. P.S.: It might include spoilers of the manga since I am not sure if Act II Second season might come out. Also, regarding to Haikyuu's spoiler, I might only write it down after the movie comes out (mostly Nekoma vs. Karasuno match, like and special chapter or something). You might also find terrible grammar mistakes.
