[Kamen Rider + System + the spirit of a Kamen Rider + protecting others]
The protagonist only thinks of the System when he needs it. The Kamen Rider forms and skills in the story may differ from the original.
“I’ve been through so many battles. I can adapt to anything! Even if I can’t win, I can still retreat! But you’re different, Miwako! I can’t... I can’t bear the risk of losing you again! Once was enough! Do you understand?!”
“Arashi! Don’t you get it?! If you weren’t here, what would be the point of me living on alone?!”
“I know it’s dangerous! I’ve always known! From the day I decided to be your liaison, I knew this wasn’t a game! But, Arashi, do you think fighting alone means you won’t get hurt? That you won’t face mortal danger?”
“At least you won’t put innocent people in danger!” Arashi almost growled the words. This was the deepest fear and strongest conviction in his heart.
“I’m not some innocent passerby! I’m a police officer! Natsuki Sakurai, patrol officer!” Natsuki raised her voice too, her words brimming with professional pride and unwavering resolve. “My duty is to protect the citizens and fight evil! And now, my duties also include supporting you, Kamen Rider Decade! This isn’t putting me in danger. It’s fighting side by side!”
Suzuki Arashi transmigrates to Tokyo and is suddenly attacked by the Shocker organization. At a critical moment, he awakens the “Rider System,” determined to fight the darkness alongside the Metropolitan Police Department and illuminate the world... HENSHIN! The power of Kamen Rider!
If the missing star is given to the harem, is it possible that you have to accept one from each world?
