Yoshinori Hidari

**Yoshinori Hidari** (ひだりよしのり, *Hidari Yoshinori*) is a detective who works alongside Nagi in the Narumi Detective Office as the left-hand side of Kamen Rider Double. In case of Nagi's absence, Yoshinori utilizes a Lostdriver and becomes **Kamen Rider Joker** (仮面ライダージョーカー, *Kamen Raidā Jōkā*) in his own right.

## History

### Backstory

Yoshinori comes from a family who didn’t really want him or care much about him. He had a younger brother who was two years younger than he was. This sibling was as forgotten about as he was, so Yoshinori looked out for them as well, putting their needs above his own. However, when the family wanted to move, the kids were put into the foster care system, and were separated. They haven’t seen each other since and have no idea where the other is now.

Yoshinori was taken in by a private detective who saw something in Yoshinori and this detective became his father figure and mentor. Yosh wanted to follow in this detective’s footsteps and become as great a detective as he was.

Tragedy would strike for Yoshinori years later on one of his first times going out into the field. Yoshinori and his mentor discovered Nagi and freed her from her imprisonment. However, a reckless action on Yoshinori’s part would cost him his father figure and mentor, as he was shot by a dopant and died in Yoshinori’s arms. Yoshinori was devastated and was tugged into hiding by Nagi. Nagi opened a suitcase she’d discovered, revealing a driver and Gaia Memories. The duo transformed for the first time and got away from there.

Not very long afterwards, the agency that had once belonged to Yoshinori’s mentor was now his, and a few months later, Yosh reopened the agency. He and Nagi work together to avenge Yoshi’s mentor and defeat the Dopants and any other threat to their city that crosses their path.

## Personality

Yoshinori's decisiveness and honed detective intuition make him a remarkable detective, even without the help of his partner. However, his emotions tend to get in the way of making the cruel yet necessary decisions that real hard-boiled detectives would have little problem making. Due to his aspiration to be hard-boiled, Yoshinori usually tries to be the serious and cool-looking one in his group, but that often results in him often being the one who is being made a fool of by others, his friends and enemies alike.

Yoshinori shows great capacity for emotion and empathy. Because of his emotional side, he is capable of understanding the emotions and actions of others. Overall, his empathy is enough for him to save all those in need, refusing to allow anyone's death if he can help it. This extends to criminals as well, hoping for each to repent their crimes and start anew with their lives. Yoshinori tries to save everybody and refuses to kill unless there’s no other options left. His hesitancy to kill can sometimes leave him vulnerable or open to enemy attacks, especially if his enemy is one not afraid to kill, or wants to kill one way or another. Yoshinori wants to become the best private detective he can be, make his mentor proud, and live up to the legacy that he was left to fulfill.

**CycloneJoker** (サイクロンジョーカー, *Saikuron Jōkā*) is the primary and default form used by Double. It is colored green and black from the Cyclone and Joker Memories, hence known as the **Fast Skilled Warrior** (迅速技戦士, *Jinsoku Waza Senshi*). CycloneJoker is considered to be the most well-balanced, thus making it Double's default form, despite being capable of initiating transformation with any set of Double's Gaia Memories.
This form has two finishers:

* **Joker Extreme** (ジョーカーエクストリーム, *Jōkā Ekustorīmu*): After inserting the Joker Memory in the Maximum Slot, Double's body splits down the middle as the halves descend on their target. A variation of this attack involves Double jumping off the back wheel of Kamen Rider Accel BikeForm, allowing for faster acceleration upon descent.
