Idomu is the oldest son of the Yudaiji group, which is second in wealth to the Imonoyama. He is an anime only character, not included in the original CLAMP School Detectives manga.

The CLAMP school, with its integrated curriculum from kindergarten to post-graduate studies, was founded by the largest of Japanese business empires, the House of Imonoyama. Funded entirely out of its own deep pockets, it was hoped that the school would be a haven for young men and women on whose shoulders our future would rest. 
The School is open to any talented individual, irrespective of his or her lineage or financial standing and is known to count scores of singularly talented pupils. It is furthermore also famous for its harboring of a remarkable percentage of party animals. Not even the bright and talented minds of CLAMP School can keep the campus free of crimes and mysteries. Or can they? Join Nokoru, Suoh and Akira, our case-cracking kid detectives, as they save the day and even the odd damsel in distress!
