Tsukioka Izumi

Key Emotion: Curiosity
Rank: S-rank

Izumi is Yuuji's childhood friend and classmate who is a carrier, carrying Rapunzel's spirit inside her. Her family is wealthy, and she is often treated around like a real princess to the extent where she was practically confined to her house. Due to this, she wasn't able to satisfy her curiosity, and to Izumi's luck (or misfortune), her trigger emotion is "curiosity". Being an “S-ranked Princess”, which means she is extremely dangerous, this curiosity transforms her into a wild and frantic girl craving to satisfy her desire to learn, and usually involves attacking the people who get in her way with her hair.

Spoiler

She later turns into an SS-ranked princess, and gains the ability to make the world loop (in other words, cause time loops).
