Mori Calliope (森 カリオペ) is one of the most iconic and influential VTubers in the world, representing hololive English (ホロライブ) as its original reaper idol. She officially debuted on September 12, 2020, and has since become a cornerstone of hololive’s global success, earning a reputation as both a powerful artist and a dependable leader within the group.

Standing at 167 cm (5’6″), Mori Calliope celebrates her birthday on April 4 and is affectionately supported by her fanbase known as the Dead Beats. While her design and stage presence exude cool confidence, Calli is widely known for her hard-working, serious, and “never-sleeping” personality, constantly pushing herself to improve and deliver high-quality content to fans around the world.

Mori Calliope is internationally recognized as a world-famous singer and rapper, blending sharp lyricism with emotional depth. Her hit songs such as “Excuse My Rudeness, But Could You Please RIP?” and “End of a Life” showcase her versatility, ranging from aggressive rap energy to heartfelt storytelling. Her musical impact extends beyond VTubing, solidifying her place as a legitimate artist in the global music scene.

A passionate gamer, Calli is a huge fan of the Persona video game series, a love that culminated in an incredible milestone when she had the opportunity to collaborate and sing with Lotus Juice, the main vocalist of Persona 3. This collaboration was a dream come true for both Calli and her fans, further cementing her crossover appeal.

Within hololive English, Mori Calliope is often referred to as the “dad of HoloEN,” a title that reflects her role as a reliable mentor and emotional pillar for her fellow members. Despite her cool and serious image, she is also famously bullyable, frequently teased by other EN members—most notably GiGi Murrin—much to the amusement of fans.
