OVA
Description
Kurumi Kasuga is the younger twin sister of Kyosuke Kasuga and the fraternal twin of Manami Kasuga. She belongs to a family of espers whose paranormal abilities, known simply as "The Power," have forced them to relocate many times to avoid discovery. Kurumi herself is a student at the same junior high school as her siblings, where she shares a classroom with Hikaru Hiyama and Yusaku Hino.

In personality, Kurumi is the polar opposite of her calm and reserved twin Manami. She is energetic, impulsive, argumentative, and endlessly curious, often acting with the unrestrained enthusiasm of a much younger child. This tomboyish restlessness makes her the troublemaker of the Kasuga household. Unlike her brother and sister, who strive to conceal their abilities, Kurumi feels entirely comfortable using her powers whenever an opportunity arises, frequently with no thought for the consequences. Her reckless levitation of furniture during a move or telekinetically messing with vehicles demonstrates a playfulness that routinely leads to chaos. The family’s seventh relocation, for example, was triggered after she openly cheated in gym class with her powers.

Kurumi’s motivations are simple: she craves excitement and instant gratification. She is driven by a desire to explore and entertain herself, whether that means snooping on a street confrontation or pulling pranks with her telekinesis. While she is not malicious, her lack of foresight regularly creates crises that her brother Kyosuke must then manage, tying her actions directly to the series’ many comedic entanglements.

Her key relationships center on her immediate family. She is deeply bonded to her twin sister Manami, though their contrasting dispositions often place them at odds. With Kyosuke, she shares a typical sibling dynamic, affection mixed with exasperation; he is frequently the one left to deal with the fallout of her antics. Their father, Takashi Kasuga, does his best to keep the household stable despite Kurumi’s disruptions. Outside the family, she interacts with her classmates and occasionally with Jingoro, the family’s cat, but her most defining interactions involve her siblings reacting to the trouble she causes.

As a supporting character, Kurumi does not undergo dramatic personal development. She remains the consistent spark of comedy throughout the story, her mischievous behavior unwavering. Her role is to inject chaos into the slice-of-life romance, and she fulfills it reliably, never losing her spirited essence.

Kurumi’s esper abilities include telekinesis and teleportation. She can lift and move objects with her mind, slow down speeding motorcycles, and swap locations in an instant. These powers are shared by her siblings, but Kurumi wields them with a distinctive lack of restraint, making her the most visible and accident-prone member of the Kasuga family.
