Description
Chidori is a significant character from the anime Go! Go! Loser Ranger!, initially introduced as an informant for the Green Battalion before his true identity as the Green Keeper is revealed. He holds the rank of First Class Ranger and serves as the leader of the Green Squad, making him one of the five Dragon Keepers who command the Ranger Force. In his public role as a Ranger, he specializes in stealth combat and invader subjugation.

Chidori is portrayed as a mysterious individual with a hidden past. Police databases show a prior arrest record, but suspiciously, much of the associated data has been erased or is missing. Even within the Ranger organization, his complete background is not widely known, as he operates secretly as an information broker, searching for intelligence on remaining threats. His early life included a period as a member of a band, where he used the stage name The Changed Real.

In terms of personality, Chidori displays a notable duality between his civilian life and his transformed state as a Ranger. When not in his Green Keeper form, he is relatively calm, friendly, and easy to trust, living quietly with his wife and young daughter in a secluded house in the forest. Upon transforming into the Green Keeper, however, his personality shifts dramatically to become high-spirited, energetic, and even noisy. Despite this change in demeanor, he remains a formidable leader whose role in the story deepens as the series progresses.

Chidori's motivations are closely tied to protecting his family and uncovering hidden truths about the ongoing conflict. His secluded home life represents a vulnerable side that he keeps separate from his dangerous work as a Ranger and informant. The revelation of his double life creates significant conflict, particularly when other characters, including Fighter D, are given opportunities to assassinate him. Witnessing Chidori with his happy family directly challenges the resolve of those sent to kill him, highlighting how his role as a husband and father complicates the black-and-white morality of the Ranger-invader war.

Within the story, Chidori serves as both a leader and a key target. As the Green Keeper, he wields a massive divine weapon known as Wrath's Hammer, which houses the Green Dragon Fafnir. His power is immense, capable of defeating major threats such as the boss monster Magatia, and his reveal as the Green Keeper marks a turning point in the narrative arc. In his informant capacity, he possesses a set of specialized tools that aid his covert operations, including a tablet containing past news called Sloth's Brain, a moving miniature lizard camera named Greed's Eye, a pistol known as Envy's Medicine, a mobility device called Gluttony's Spy, and his primary green divine weapon.

Chidori's key relationships include his wife and young daughter, who represent the personal stakes behind his public duties. The TV Tropes history page names these family members as Sanae and Momiji. His identity as the Green Keeper and his presence in their lives provides them with a level of protection from other threatening organizations, such as the Rangers Association. His relationship with Fighter D is particularly complex, evolving from that of a target to a figure who inadvertently causes D to question his mission objectives after witnessing Chidori's family life.

Throughout the series, Chidori undergoes development primarily through the exposure of his secret identity. Once unmasked as the Green Keeper, previously separate aspects of his life as the calm informant and the powerful Ranger converge, forcing both himself and those around him to reconcile these two facets of his character. His continued survival and his role as a Dragon Keeper ensure that his actions have far-reaching consequences for the broader conflict between the Ranger Force and the invader armies.
