Kagero

## Appearances

**Kagero** (カゲロウ, *Kagerō*) was Daiji Igarashi's inner demon who transformed into **Kamen Rider Evil** (仮面ライダーエビル, *Kamen Raidā Ebiru*). He is the manifesation of Daiji's self-doubts and hidden resentment towards Ikki.

## History

### Background

Kagero was the inner demon born within Daiji Igarashi and stems from his resentment towards his older brother, Ikki Igarashi. While Daiji admired Ikki, he felt outshined by his older brother and motivated him to enlist in Fenix. However, Ikki would go onto become a Kamen Rider when Daiji hesitated in equipping the Revice Driver. Eventually, the resentment grew stronger and his inner demon managed to take over Daiji's body.

### Peril of Kamen Rider Evil

At the Fenix Skybase at night, the Kagero-possessed Daiji stole Hiromi Kadota's ID to steal the Lion Vistamp, that led to the creation of the Lion Deadman. During a stakeout by Fenix, Kagero would be given the Two Sidriver by George Karizaki to become Kamen Rider Evil. The mysterious Rider attacked Kamen Rider Revi and Kamen Rider Vice in his first transformation. Afterwards, Kagero later meets with the Deadmans and expressed to work together out of shared interests.

He would continue fighting Revice as Kamen Rider Evil, all while pretending to be Daiji to the rest of the Igarashis. Fenix caught wind of Kagero's presence and deployed Hiromi Kadota as Kamen Rider Demons to subdue him. During the Igarashi's family vacation, Kagero revealed himself in front of everyone and attacked Ikki. While Ikki was reluctant to fight him, Kagero revealed Daiji's resentment towards Ikki taking away his chance at being a Rider. While Kagero plots to contract with a trio of scammers to unleash the Brachio Deadman, Evil was subdued after Ikki motivated Daiji to overcome Kagero's shackles.

Following his defeat by Revice's Brachio Genome, Kagero would occasionally resurface to cause trouble to the Igarashi siblings. He made his return after Daiji was knocked unconscious from protecting Sakura Igarashi, though she was able to upturn him back with a Rider Kick. This phenomenon is later made known to Ikki, which he uses to summon Kagero. He would disclose the method to enter the Deadmans' base in exchange for Sakura's spicy curry.

After Hiromi's apparent demise, Kagero appeared to Daiji and offered to take over, in which Daiji refuses. Later, he temporarily took over Daiji's body to help him fight Orteca, who become the second Kamen Rider Demons, reasoning that if Orteca manages to kill Sakura, then Kagero cannot taste her curry anymore. Ultimately, Kagero was defeated, though he managed to do some damage to the latter.

### Final Foray Against Daiji

*"Daiji... Farewell."*
    ―Kagero's last words to Daiji before his death
When Kagero resurfaced for the last time, he confronted Karizaki to demand the Two Sidriver's enhancement item using Akemi Mikoshiba as a hostage. Director Akaishi decided to allow Kagero to take the Crow Vistamp, and he separates Daiji from himself in a battle for supremacy. The two transform and battle fiercely. However, Live gradually overwhelms Evil, and Evil strived not to hesitate despite his poor condition. After being defeated, the dying Kagero gives Daiji the Holy Wing Vistamp before vanishing.

## Personality

In contrast to Daiji, Kagero is blunt, cold, manipulative and amoral, often seen with a sadistic smile. He does not think highly of his host, calling him an idiot. He is cold in demeanor and shown to be a skilled manipulator.

Being born from Daiji's suppressed resentment towards Ikki, Kagero's ultimate goal is to kill Ikki. He often mocks his "brother" for playing the hero role, and mockingly addresses him as "Big Brother". Even so, Kagero has proven to be patient, as he was able to enjoy his stay with the Igarashi family for a moment and plan his reveal at the best possible moment. However, it is shown that he wants to be the one to kill Ikki, as he stopped Aguilera from poisoning his target, and later confronted her and the Deadmans for doing so.

Despite working with the Deadmans at first, Kagero was willing to aid the Igarashi siblings in some scenarios if it involved Sakura's spicy curry (which instantly becomes his favorite food), such as revealing the location of the Deadmans Base and even protecting Sakura from an incoming Orteca. In his last moments, he gives his host the Holy Wing Vistamp so Daiji can defeat Orteca.

While active in Daiji's body, Kagero has a habit of flicking his index finger.

## Powers and Abilities

### Powers

* **Demon Physiology**: As a demon, Kagero possesses the following characteristics:
	+ **Possession**: Initially, Kagero was able to take control of Daiji's body completely, through the latter's hidden resentment towards Ikki, which was built up over time. After Daiji managed to gain control of his inner demon, the two are now able to switch places whenever Daiji's physical body receives a strong enough force to knock him out and render the dominant personality unconscious.
	+ **Enhanced Strength**: Kagero is shown to be incredibly strong, as he was able to overpower Vice in battle and sent him flying in a single hit, and damaged Orteca when Live was not able to.

### Abilities

* **Skilled Acting**: Kagero is shown to be a convincing actor, as he was able to deceive the Igarashi family into believing that he was Daiji.
* **Expert Tactician**: Kagero was able to formulate a plan to steal Hiromi Kadota's card, as well as the Lion Vistamp from Fenix.

### Weaknesses

* **Daiji Igarashi**: Much like Vice, Kagero will die if his host, Daiji, is killed. Additionally, while Kagero's presence is strengthened by Daiji's hatred towards Ikki, the inverse can also happen as Kagero can also be weakened by Daiji's growing kindness and strength of will. Kagero could also be knocked out by a strong enough force, allowing Daiji to resume control of his body.

## Behind the Scenes

### Portrayal

* Kagero is portrayed by Wataru Hyuga (日向 亘, *Hyuga Wataru*), who also portrays his host Daiji Igarashi. As Kamen Rider Evil, his suit actor is Yuji Nakata (中田 裕士, *Nakata Yūji*).

### Etymology

* The katakana for Kagero's name translates to "mayfly", a species of aquatic insects belonging to the order Ephemeroptera.
	+ Kagero's name comes from the Japanese words for **Shadow** (影, *Kage*), as well as the suffix **Ro** (郎, *Rō*), a common male suffix for Japanese forenames.
* Evil's name defines Kagero as a villainous rider. The pronunciation of the word Evil (エビル, *Ebiru*) in this context is taken from the last letters of the Japanese pronunciation for the word Devil (デビル, *D**ebiru***).
	+ Evil could also be an anagram of Revi's name etymology, **Levi** (לוי), as well as the English definition of Vice.

## Notes

* In the shooting scripts, Kagero pretending to be Daiji is referred as **K-Daiji** (K大二, *K Daiji*).
* Series writer Hanta Kinoshita has stated that he based Kagero on a villain from a film he has yet to disclose, but was surprised to see the uncanny resemblance on-screen despite having not spoken to Hyuga regarding this.
	+ Hyuga has stated that his portrayal of Kagero is based on Loki from the *Marvel Cinematic Universe*.
* Unlike the other inner demons in the series, Kagero does not appear to have his own form separate from his host; the only time he was separated from his host, he still took on Daiji's appearance.
