Romeo is a fastidious workaholic and rationalist. He does not tolerate idlers without a thirst for self-realization and appreciates qualities such as hard work and dedication. This is one of the reasons why he finds only Kuromaku of all eight clones interesting to talk to. He has difficulty communicating, acute reactions to any touch and a tendency to loneliness. This partly explains his unsociable nature and avoidance of contact with other clones under the guise of "important things".
