YMMV / Showa & Vampire

  • Angst? What Angst?: Even after being kidnapped at young ages, being tortured and turned into cyborgs, made to kill a lot of people, and even getting killed around a year prior to the start of the story, the renegade NUMBERS have no trouble adjusting to the new environments. Although the only ones who come closer to Wangst are Daichi and Hana.
  • Designated Hero: Let's be up front about this, Shinichi and his friends are the source of the problems in this story. Their presence is what draws GIN-SHOCKER forces to the school, but they never tell anybody about the kaijin despite knowing everything, because if anybody found out they'd lose the chance to go to high school. And despite knowing that a huge evil organization is out there gathering power and destroying lives, they're not very interested in getting off campus and doing anything about it. Toward the end it seriously becomes a Once per Episode event where one of the heroes wishes GIN-SHOCKER would just go away and leave them alone. The last chapter ends with them going back to Youkai Academy to start their next year, suggesting not much would've changed if the story had continued.
  • Fridge Logic: So you start with Rosario + Vampire, a series about a secret monster world whose members are taught to avoid exposing their true nature to humanity to avoid starting wars. Then you combine it with Kamen Rider, which is all about armored heroes fighting and destroying monsters bent on the destruction of humanity. Shouldn't Kamen Riders be the very symbol of monsters' fear of humanity? It's never mentioned, and the Kamen Riders are idolized by the monsters they meet.
  • Iron Woobie: After seeing what Shinichi has suffered and yet bounced back from, albeit by repressing nearly all memory of it ever happening to him, it's plausible that he is this, as he's not The Stoic nor is he a Jerkass or an Omnicidal Maniac driven by his suffering to end the world... even if BLACK 13 has the potential to become the last one.
  • Moral Event Horizon: Seeing what was done to Shinichi to transform him into BLACK 13 is enough to convince the unlucky viewers that Dr. Gebok — and GIN-SHOCKER — crossed this in a big way.
