Leadoni is a small blue oni with a single red eye and a black horn on top of his head. He smiles most of the time and carries a tourist guide flag. He wears a dark yellow skirt with spiral patterns. His large purple hand is in a beckoning gesture.
Leadoni are known to lead you somewhere. In the games, Leadoni can lead you to a good treasure chest or a bad treasure chest that has a Yo-Kai that you must face. Anyone being led by Leadoni is said to become lost or lose sight of their original destination. In the anime, Leadoni seems to be able to lead people where they want to go, albeit through unconventional routes.
Leadoni can also be found in Terror Time as minions of Gargaros and his brothers. They wander around in search of the player, but have a poor scope of vision.
Leadoni appears in the main section of the Abandoned Tunnel, before the Watch Locks. He also appears in grass spots and under houses in Uptown Springdale.
Yo-kai Watch 2
Leadoni can be found as an overworld enemy in the Jumbo Slider area in the forest above Breezy Hills.
Yo-kai Watch Animation series
In EP053, Leadoni meets Jibanyan at a Yo-kai party off-screen; the latter subsequently introduces him to Nate and Whisper after discovering that they have become lost in Dromp's maze. Leadoni brings the group through the maze to reach Nate's house by means of absurd pathways, including walking on fences, rooftops and through neighboring houses. Some time after this, Leadoni gives Nate his Medal.
He is first summoned in EP119 to help Nate's team complete another of Dromp's mazes.
Leadoni and Mynimo belong to a category called ko-oni or shoki ("small oni" or "lesser oni"). They don't have the size and power of their larger comrades, but they're insidious, mischievous creatures that often follow them in tow and cause havoc in their wake. Additionally, his behaviour reflects the expression onikakure ("hidden away by oni"), which is the Japanese equivalent of "spirited away".
"Leadoni" is a wordplay on lead on and oni.
"Michibiki" is the word guidance in Japanese, with the last syllable replaced by the kanji for "oni".
"Noguío" is translated as not guiding.
He causes trouble for Nate and Whisper 1-4 times.
He fights them to prevent getting the Leadoni wheel.
The choices you make during the Nocturne Hospital checkup will determine if you anger him and engage in fights.
Standing on your tiptoes for height angers him.
Answering "It's a gorilla" for eyesight angers him.
Answering "It's weird" for X-ray angers him.
Even though "It's weird" is the correct answer, he still gets angered mainly because he thinks your weird heart is normal, or he wants you to agree your heart is normal even though it really is not.
Despite causing trouble to Nate and Whisper, you should still befriend him in early Chapter 2 to undo a seal for Shogunyan.
