Trivia / Yamada-kun and the Seven Witches

• Ability over Appearance: Almost all characters in the live-action show are cast like this. Of course, with the manga's array of ridiculous hair colors, it may be hard to find an actor with green hair unless they're willing to dye it, but other than that, little regard is given to whether the actors look like their characters. Only live-action Yamada looks like manga Yamada - and to some degree live-action Shiraishi who at least has the same hairstyle as her manga counterpart, but with a completely different hair color. Among other characters, it's noteworthy how Odagiri's actress looks like she should have played Asuka, and Asuka's actress looks like she should have played Odagiri.
• Cancellation: While the reason hasn't been disclosed to the public, this is what happened to the series around chapter 236, leading to a very rushed ending with lots of stuff Left Hanging.
• Dawson Casting: The actor playing Yamazaki in the live-action drama is above 30, and Rika's actress and Yamada's actor are in their mid twenties. Shiraishi, Itou, Miyamura, Asuka, and Sarushima also have actors who are a few years older than their characters. Otherwise it's reasonably averted for a show starring teenage characters.
• Flip-Flop of God: When discussing the drama series with actor Yusuke Yamamoto, Yoshikawa mentions - as a reply to Yamamoto's worry of getting too used to kissing - that Yamada indeed has gotten way too used to kissing other people. In an interview a couple of years later, she instead says that every kiss has a meaning to Yamada, and he still feels nervous every time.
• Incidental Multilingual Wordplay: Chapter 31 is titled "Odagiri's boobs" which is essentially just a line from the chapter taken out of context like with most chapters. The French translation has it easy; one French word for boobs is "nénés", and since Odagiri's first name is Nene, take a wild guess about what the chapter title is in French... Les nénés de Nene.
• Overtook the Manga:
  • The live-action drama covers the first witch war, but was produced long before the first witch war ended in the manga. The result is that while the first few episodes are relatively faithful to the manga, the last episodes are markedly different - Yamada is the one who forgets everyone instead of everyone forgetting him, the ceremony has many more restrictions (the episode with the ceremony was filmed before the ceremony was even mentioned in the manga, meaning that Yoshikawa apparently told the writers about it, but didn't tell them exactly how it worked), and the ending is nothing like the manga's ending except for the fact that Yamada and Shiraishi get together.
  • The anime was produced before the second witch war ended in the manga, but averts this trope by only adapting the first witch war.
• Portmanteau Series Nickname: The series is known as "Yamajo" (Yamada-kun to Nananin no Majo) in Japan.
• What Could Have Been: At one point, Yoshikawa planned for one of the witch powers to be a literal Gender Bender power (unlike the body-swap power which merely allows you to swap bodies with the opposite sex), but dropped the idea. Probably because changing your sex would be a power of physical change, while all other witch powers are mental and only changes the mind of the witch or their victims.
