Trivia / Sarazanmai

• All-Star Cast: In the Japanese version, popular seiyuu Jun'ichi Suwabe, Ayumu Murase, Kōki Uchiyama, Shun Horie, Mamoru Miyano and Yoshimasa Hosoya are playing characters in this Anime.
• Anime First: Played with. While a manga series and a light novel were released before the anime aired, the manga is more of a spin-off that doesn’t necessarily cover anything related to the Anime’s plot. The first light novel however roughly covers the first six episodes, plus reveals the identities of Reo and Mabu. This book was released days apart from the show.
• Incidental Multilingual Wordplay: Every episode has Keppi tell the boys to steal the kappa zombie's shirikodama with the command "kapparae!" ("snatch it!"). French just so happens to have the word "accaparer", which not only has a similar meaning but is almost an anagram and keeps the kappa pun, so the French translator went straight for it.
• Man of a Thousand Voices: In the Japanese version, all the zombies are voiced by the same man, Ryo Kato.
• Meaningful Release Date: Episode 9, focused on Chikai and Tooi, originally aired on Brother's Day in Japan (June 6).
• Non-Singing Voice: Averted with both of the insert songs for the English dub.
• Queer Character, Queer Actor: In the English dub, the openly gay Daman Mills voices the Straight Gay kappa Mabu Akutsu.
• What Could Have Been:
  • For episode 2, Tooi was going to be momentarily possessed by the Cat Zombie and try to decapitate Enta with a huge pair of scissors.
  • Official storyboard art shows that Reo and Mabu were initially going to dance up an escalator for their "Kawausoiya" part. The artbook further elaborates that the scene was supposed to be more musical inspired, with the dance instead being a musical number and the theme being more The Phantom of the Opera inspired. The musical theme is given a nod in Episode 9, where Reo dances and sings home with moves straight out of West Side Story.
  • Enta's sister Otone and the boys' homeroom teacher were not originally the same person. There was also a point in time where Otone would have been friends and classmates with Sara.
  • Keppi would have had coloring more similar to a typical kappa in his concept arts, and the Wi-Fi symbol would have been on his head from the start; the design itself remained largely the same. In the art book, his early name would have been written as "KP".
  • The transformation sequence would have had the boys' human bodies being blown off and burned away, to make their kappa forms' "dead yet alive" motif more apparent.
  • Chikai would have been a little younger in the earlier drafts, with a look that's more delinquent like than gangster like.
• Word of God:
  • According to staff commentary from the first anniversary livewatch, the member of the Yurikamome who tried to attack Chikai and Enta in episode 8 is named Yasuda Yasu.
  • The two gangsters alongside Taka in his betrayal of Chikai are named Taku and Kou, and were also former members of the Yurikamome who wound up joining Chikai's group after Kamome's death.
