Kureichirō Ebisugawa is the eldest son of Sōun Ebisugawa and a member of the Ebisugawa tanuki family. He is the older brother of the twins Kinkaku and Ginkaku, as well as Kaisei. Long before the events of The Eccentric Family 2, Kureichirō had a falling out with his father, finding his scheming and underhanded ways unbearable, and left the family to wander the Shikoku province alongside the Kinchō family. Because of this prolonged absence, he was not in Kyoto when his father’s schemes reached their peak or when Sōun died. After his father’s death, news was spread that Kureichirō had returned to Kyoto to succeed as head of the Ebisugawa family and, together with Yaichirō Shimogamo, worked to restore peace between the Ebisugawa and Shimogamo families. In truth, the Kureichirō who first appeared as the new family head was Sōun himself, using his tanuki shapeshifting to impersonate his estranged son in order to continue manipulating events. The real Kureichirō remained away until his younger brother Yajirō Shimogamo encountered him during his travels, after which the genuine Kureichirō finally returned to claim his rightful place.

As an individual, Kureichirō stands in stark contrast to his father. He is unwilling to participate in deceit and chose to sever ties rather than be complicit in Sōun’s machinations. This moral backbone suggests a principled and independent nature, even if it means hardship and isolation. Once he truly assumes the role of Ebisugawa head, his motivation shifts toward genuine reconciliation rather than power games; he takes the steps necessary to end the feud between the two tanuki families, showing a desire for harmony and a break from the toxic legacy left by his father. His relationship with his siblings is one of reluctant distance, having been absent during their upbringing, yet he returns to a family that needs leadership, and he accepts that duty. His interaction with Yaichirō Shimogamo is particularly notable, as the two of them orchestrate the public reconciliation that formally ends the hostility, and in doing so he earns a measure of respect from the Shimogamo household.

Kureichirō’s character arc is largely one of delayed arrival and quiet rectification. He is not a boisterous or eccentric presence but rather a corrective force who emerges in the aftermath of the main conflict to set things right. His return from Shikoku marks the point at which the fake Kureichirō is exposed, and his calm assumption of the family head role signals the start of a more honest era for the Ebisugawa clan. As a tanuki, he possesses the typical shape-shifting abilities of his kind, capable of transforming into humans, objects, or other creatures, though the narrative does not highlight any unique or extraordinary transformations specific to him. His real strength lies in his quiet resolve and his willingness to walk away from corrosive family dynamics, then return only when he can make a positive difference.
