Kamen Rider Discussion

Regarding the Ryuki novel, it's an AU.
Ryuki, Knight, Zolda, Ouja and Femme are the main Riders. Imperer, Raia and Scissors are mentioned but die literally immediately. Their human forms aren't even named. Shinji actually kills Imperer and doesn't regret anything.
Differences here and there. Shinji is a jack of all trades instead of working for ORE Journal. Ren and Yui are friends with benefits. Ren is still together with Eri while banging Yui on the side. Kitaoka has alzheimers. Goro's mouth is sown shut with a golden wire, and can't speak. There are no cards at all. They transform with an emblem in front of a mirror and jump straight into the Mirror World. Apart from everything is mirrored, there is no sound in the Mirror World. They're not called Kamen Riders. Instead it's Kamen Keiyakusha (Masked Contractor), altough it does say Rider in smaller katakana next to the kanji. Asakura makes you instantly realize it's Inoue behind this book. He's the embodiment of Inoue characters, reminds me a bit of Kusaka from the Faiz novel. Not the whole rape thing, but his personality.
Femme asks Shinji to pretend to be her boyfriend, they end up dating for real and have sex.
Still the same battle royale, the ending is nearly identical to the TV series. It's not too different from the TV series, it's just 10 times edgier with unnecessary sex and violence.

It's telepathy or whatever instead. They just summon things.
It's lighter than Faiz, but still graphic. Inoue barely goes in on Kanzaki and Odin is not mentioned, it's just those I wrote down.
Goro's mouth being sown up is because of his respect for Kitaoka. After finding out Kitaoka's sick, he gets his mouth shut so no one will find out about the illness. Hence, why it's gold. Silence is gold and all that.
It gets worse. Yui is Eri's nurse. Yui even says "Ren already has Eri, so he'll never truly love me. But I'm okay with that."
Asakura kills his own mother, 7 days after he's born. Yeah, 7 days.
Femme is treated a lot better in the novel, which is good.
The emblem has a symbol of a Mirror Monster on it, and they contract with the monster. There's 9 rules you must follow once you contract, one of those explains that.
