  • As Mizuno is designed by Seiichirou Yamashita, the voice actor of Yukimura Rekka, her cost, each level's BP, and all level costs are the same as Yukimura's key Spirit, The SengokuDragon Souldragon.
  • Along with The StarAngeliaGoddess Ishstar and EternalRainbowCoord Nijino Yume, they are the Yellow-only Spirits/Ultimates with the highest BP.
  • The name "Mizuno" comes from the protagonist, Takahiro Mizuno, from the adult visual novel, Walkure Romanze, which was the first character that Seiichirou has done his voice-acting on.
    • Hence, Mizuno's title "Sincere Valkyrie" comes from the novel's title "Walkure", which means "valkyrie".
    • The mention of "freelance" in the flavour text may be a reference to the use of lance in the novel.
  • During Seiyuu Lovers of Battle Spirits Broadcast on 27/2/2016, Seiichirou first designed Mizuno, and described her as "an existence similar to a daughter".
  • Mizuno later on also had another card, which is Mizuno-san of the Toilet.
