U-Ikasaman was a Daimon supervised by Mimete. She was the head of the dimensional rift created in the Tomoe residence after Mimete shoved a variety of random items, mostly board games but also books and a rice bowl, into the Daimon-creating oven while Professor Tomoe was not looking.
Apparently, she could manipulate the entire dimensional rift at will, threatening the Sailor Senshi that she would fling them off into another dimension if they did not play her games. U-Ikasaman claimed to be a pacifist, and said she did not like to resort to violence, but that did not stop her from sealing those who lost her games into giant playing cards.
She played games with the Sailor Senshi, but used methods of cheating to beat all of the Inner Senshi. After she lost to Chibiusa and Hotaru, she went back on her word and refused to let everyone go. Chibiusa then transformed into Sailor Chibi Moon and released Sailor Moon, who destroyed U-Ikasaman and the dimensional rift on the house.
- "Ikasama" (いかさま) means "cheat" in Japanese, making the Daimon's name a nod to her tendency to rig her games with the Sailor Senshi.
- Her character design was similar to that of a queen from a deck of playing cards, which fit her fondness for them as well as her tendency to seal losing opponents into oversized cards themselves.
- U-Ikasaman was the only Daimon that did not not attack a victim for their Pure Heart Crystal, as she was created in a lab accident and not for a specific target.
