Description
Bakumaru, full name Bakuretsumaru, leads the Eto Rangers as Ranger Number 1 and primary protagonist. He earned this position by winning the decisive race to select the twelve animal spirits protecting Mugen. As the anthropomorphic mouse spirit representing the rat in the Chinese zodiac, he possesses light purple skin, brown hair, and blue eyes. His attire consists of a blue vest, white tunic, white gloves bearing his Ranger badge on the left, and a distinctive red visor hat.

He exhibits a strong sense of justice and heroism, frequently tempered by impulsiveness, arrogance, and recklessness—often charging into battles beyond his skill. Despite this, he maintains a fundamentally compassionate nature and deep care for his companions. A defining trait is his debilitating ailurophobia (fear of cats), stemming from persistent childhood bullying by the cat spirit Chocolat. This trauma initially caused him to faint upon encountering feline adversaries like the Jyarei monster Genen.

His character development focuses on overcoming this fear. Guided and trained by Gaou, the tiger spirit Ranger, Bakumaru confronts his phobia in Episode 21, enabling him to face feline enemies directly. This breakthrough coincides with developing his signature mid-air spinning attack, the "Bakuretsu Shippuken" (Explosive Gale Sword or Killer Hurricane), executed with his Light Saber.

His combat relies on agility, resourcefulness, and specialized equipment. Key tools include the Revealing Mirror, which both exposes disguised Jyarei monsters and summons backup Rangers not on missions, and the Light Saber acquired during the Momotaro Novel World mission (Episode 2). The Light Saber enables techniques like the Reckless Cut, where he spins it like a fan to deflect attacks. His Ranger badge summons the transport Kirinda to purify defeated monsters and contributes to the Rangers' combined beam attack.

Interpersonal dynamics significantly shape his journey. He shares a mutual attraction with Cream, the rabbit spirit Ranger, sometimes prompting jealousy from her. His Ranger relationships range from camaraderie with Gaou to mediating conflicts between Monk and Pochiro. Bakumaru also narrates the series, delivering titles, recaps, and previews.

In the final arc, Bakumaru demonstrates critical leadership and emotional growth. After Nyanma (the corrupted Chocolat) eliminates most Rangers, he survives alongside Cream and Urii. During the climax, he appeals directly to Chocolat's lingering humanity by revealing Bagi's manipulation in her disqualification from the zodiac race. This approach, contrasting with others solely calling her "Nyanma," showcases his evolved perspective. His intervention resolves the central conflict, fulfilling his role as the unifying Eto Rangers leader.
