YMMV: Diamond no Ace

  • Arc Fatigue: The game against Inashiro Tech is several volumes long. It's made even worse when after all the tension build-up, they lose cuz they blew the save. It's not as bad in the anime, lasting more or less ten episodes; which is only about twice as long as the other games, which average around 4-6 episodes. You still get the heartbreak when Seido loses, but it's still nowhere near as long and upsetting as in the manga.
  • Bishonen Jump Syndrome: The character design certainly evokes this, especially compared to the other sports anime that aired in the same season, Yowamushi Pedal. However, in comparison in other sports animes, it isn't much.
  • Ensemble Darkhorse:
    • You'd be pressed to find someone who doesn't like Chris Yuu Takigawa. A good portion of the fandom calls him Chris-senpai not just because that's how Eijun calls Chris, but simply out of respect for him.
    • While all of the third-years are quite popular, Ryousuke Kominato and Tetsuya Yuki are particularly well-liked.
    • The Yakushi team also has a respectable amount of fans, especially Raichi and Sanada.
  • Ho Yay: The boys seem to be passionate about each other.
  • Launcher of a Thousand Ships: Eijun, Eijun, Eijun; there's Eijun x Chris, Eijun x Furuya, Eijun x Miyuki, Eijun x Haruichi, Eijun x Wakana, Eijun x Haruno, and the list goes on.
    • Haruichi as well; Haruichi x Eijun, Haruichi x Furuya, Haruichi x Ryousuke, and the list goes on, it also doesn't help Haruichi that he's a Dude Looks Like a Lady.
    • Miyuki isn't far from this as well. There's Miyuki x Eijun, Miyuki x Chris, Miyuki x Furuya, Miyuki x Narumiya, Miyuki x Kuramochi and Miyuki x Norifumi, and those are the popular ones.
  • Periphery Demographic: Like most sports anime, no one besides prepubescent yaoi fangirls seem to take it seriously.
  • One True Threesome: Eijun, Furuya, and Haruichi; extra points since whenever Haruichi compliments one of the them, the other gets jealous and fuels their rivalry.
    • Eijun, Furuya, and Miyuki.
    • Eijun, Miyuki, and Chris.
    • Just find three characters that are close and they fit this.
  • The Woobie:
    • Eijun is usually energetic and cheerful, but when he takes a hit, he takes it hard, and it's nearly impossible not to feel sorry for him. Two examples in particular would be: when Raichi hits a home run out of his pitch, and when he accidently hits Shirakawa in the head during the Inashiro game, which later causes him to develop Yips.
    • Furuya. Before joining Seido, his teammates refused to play with him because he was too strong, leading him to train all by himself.
