Guidoro is the Zoozian clan leader who appears in the anime series Endride. The character is sometimes referred to as Guidoro, a variation likely due to transliteration. During the events on Gradido’s boat, Guidoro is shown to be an ally who has reunited with the main group known as the Ignauts.

Guidoro’s role in the story is defined by the immediate conflict sparked by his presence. He is confronted on the deck of the ship by two other characters, Mischa and Felix, who are upset that he has joined the Ignauts, even if only temporarily. This confrontation reveals that Felix and Mischa harbor a deep distrust for Guidoro, which is noted to be as strong as their distrust for another character, Louise. The situation escalates into a scuffle where weapons are drawn, despite attempts by Louise and Eljuia to mediate and prevent a fight.

The conflict is brought to an end when Demetrio and Gradido arrive. Gradido proposes that he will take responsibility for Guidoro and Louise’s actions, and then requests to join the Ignauts himself, a request Demetrio readily accepts. This act suggests that while Guidoro is an ally whose presence is contentious, he is vouched for by a trusted member of the group.

Following this resolution, the Ignauts travel to the Zoozian island, where they easily defeat a regional lord who is attacking it, putting an end to the assault. The group later relocates to Gradido’s home, where Guidoro is presumably present, as the focus shifts to planning their next moves to head to the capital and address unrest in various territories. A character named Chum, who is revealed to be Gradido’s son, also appears. No further information is available about Guidoro’s background, personality, deeper motivations, personal development throughout the story, or any notable abilities.
