Alain

Alain (アラン) is one of the sons of the Grand Imperial Majesty Adonis, and is referred to as the "prince" of the Ganma. He worked with Chikara Saionji, who was himself aware of the Ganma and Ghost Eyecons, prior to the latter's death. He later gains the ability to transform into Kamen Rider Necrom (仮面ライダーネクロム).

Pre-series events
At some point, Alain crossed over to the human world, and began working with Chikara Saionji, a human with knowledge of the Ganma. Aran promised to help Saionji collect the 15 luminary Eyecons in exchange for Saionji's help in the invasion of Earth. At an unspecified point in time, Alain met and befriended Makoto and Kanon Fukami, two humans who had been sucked into the Ganma World.

Beginning the Invasion of Earth
Alain was placed in charge of setting preparations for the invasion of the human world. While it is unknown to what extent he completed his plans, Alain eventually ran into an obstacle in the form of Takeru Tenkuji, who became Kamen Rider Ghost after being killed by the Katana Ganma. Alain witnesses the destruction of the Katana Ganma at the hands of Kamen Rider Ghost who had acquired the Musashi Eyecon, noting to Chikara Saionji that an obstacle to their agenda has emerged. Later, Alain sees the Denki Ganma fall to Ghost as the Kamen Rider claimed the Edison Eyecon it sought. Voicing to Saionji that his efforts in manipulating Yoshinori Sonoda were for naught, Alain is assured by him that his endeavor was in fact quite productive and that it would prove useful in the long run. Becoming increasingly tired of disappointment as he witnesses the Ono Ganma be destroyed by Ghost now in Robin Damashii, Alain tells Saionji, who now appears unnerved, that he has had enough of his excuses.

Tired of Saionji's failures, Alain begins to take matters into his own hands. While the Book Gamna's manipulations send a large portion of the city into the sky, Alain sends out multiple Eyecons. He seems unfazed by Ghost defeating the Gamna, saying that it was only a taste of what is to come. Saionji confronts Alain sometime later about Kamen Rider Specter taking the Nobunaga Eyecon. Aran reassures his partner that he would fulfill his side of the deal, warning Saionji to do the same. After Saionji departs, Alain launches Ganma to take over a city hall, in order to use the location for a Ganma Hole. When Specter stops Ghost from interfering in his plans, Alain personally gives his thanks, and asks for additional help. After Specter declines, Alain ponders about the importance of the luminary Eyecons. Although Specter later removes the Ganma from the location, Alain overlooks his action due to the preparations already being complete.

However, in his next encounter with Specter, he asks whether or not he could count on him. Specter lends him the Edison Eyecon to use for his plans, although Alain admits his uncertainty about Specter's final goal. Some time later, Specter calls him asking for information on Saionji. Alain only states that Saionji is helping him, but returns the Edison Eyecon, which he has used to create a monolith. The monolith is destroyed when Ghost defeats the Insect Ganma, in order to prevent Takeru from investigating it.

Aftermath of Saionji's Betrayal
Jabel's actions alerted Alain that the luminary Eyecons had powers he was unaware of. Confronting Specter a final time about his new alliance with Takeru, he warned his former friend that they would be enemies the next time they met. Alain took the Eyecons Jabel had recovered before going to see his brother, warning Jabel not to take any action until he returned.

Personality
Alain is cool and calculative as far as observing the Ganma do their thing to wreak havoc in human society. However, he is also temperamental and not without tolerance for failures; where he employs Chikara Saionji to do his bidding constantly backfires due to the presence of Kamen Rider Ghost foiling their plans. Alain is shown to not to tolerate any form of insubordination and treason, such his enforcer, Jabel who took course of action of taking two Ghost Eyecons and attacking Ghost and Specter using the Gundari without his consent; with Alain forcing to Jabel to stand down ; as well as Makoto deciding to join forces with Takeru after the latter used the 15 Heroic Eyecons to revive his sister, ultimately severing their ties.

Alain's demeanor changes as he grows increasingly frustrated with Takeru's interference,

Despite severing ties with Makoto, Alain is still on cordial terms with Kanon.
