Well, Wattpad can also be a good place to look for Haikyuu fanfiction. There are many writers on Wattpad who create interesting stories based on the Haikyuu characters. However, the quality can vary more compared to AO3 or FanFiction.net. Another option could be Tumblr. While Tumblr is more of a blogging and sharing platform, there are a lot of fanfiction writers who post their Haikyuu works there, often with some really cool fan art to go along with it.
First, make sure you have a clear understanding of the Haikyuu characters and the basic plot of the original work. This will help you better appreciate the fanfiction. Then, try different genres of fanfiction, like romance, adventure, or AU (alternate universe). Also, engage with the community. Leave comments on the fics you like, and you might discover more great stories through the discussions.
They might be really surprised. Some characters could be amused by the creative scenarios fans come up with. For example, Hinata might be excited to see himself in all kinds of wild adventures in the fanfictions.
The characters might be a bit shy. For instance, if there are fanfictions about Tsukishima and Yamaguchi's friendship, Tsukishima might act like he doesn't care but secretly be a little flattered. Yamaguchi, on the other hand, would probably be more openly happy about it.
One great 'Haikyuu Yachi Fanfiction' is 'Yachi's Growth'. It shows her journey of becoming more confident in the Karasuno team. Another is 'Yachi and the Volleyball World', which dives into how she experiences the intense volleyball matches from her unique perspective. And 'Yachi's Hidden Talents' is also a good read, exploring some skills of Yachi that we don't get to see much in the original anime.
One of the best is 'The Volleyball Dreamers'. It has great character development and really dives deep into the team dynamics during the games. The story follows an alternate universe where the characters face new challenges on and off the court.
A good Haikyuu fanfiction should have accurate character portrayals. Since the fans already know the characters well from the original series, any deviation without a good reason can be off - putting. For example, Hinata should still be that energetic and determined player.
Sakura Haruno might have a unique role in a Haikyuu fanfic. She could be someone who bridges the gap between different cliques in the school. Since she is used to dealing with different personalities in Naruto, she could use that experience to make the volleyball team more united. She could also be involved in fundraising activities for the team, using her charm and persuasion skills.
One great Haikyuu male OC fanfiction is 'The New Rival on the Court'. It has a well - developed male OC who joins Karasuno and brings a new dynamic to the team. His backstory is engaging, and his interactions with the canon characters are really interesting.
