Igarashi Rika

Igarashi Rika (五十嵐梨花) is a Japanese Virtual YouTuber affiliated with NIJISANJI, debuting as part of the unit "Idios" (いでぃおす) alongside Koshimizu Toru, Ishigami Nozomi, Sophia Valentine, Kuramochi Meruto, Kaburaki Roco, and Shishido Akari.

Profile
Rika is a gyaru and always energetic. She often walks outside to find something fun. Mesh highlights in her hair are innate.

Lore
Rika is a salesgirl of beers at a certain ballpark who loves subcultures. She used to enjoy watching anime and playing video games at home during her free time, but one day she started to feel unsatisfied at her life being a repeat of those. As she started searching for some videos on internet, she found "The First VTuber Girls' Lotion Sumo Wrestling Tournament" by Honma Himawari, introducing her to NIJISANJI and making her decide to become a Virtual Liver.

Personality
Rika likes to talk so much that she sometimes talks uncontrollably, especially when playing games that develops in a moment like Mario Kart, but instead of her speech becoming out-of-context or uttering nonsensical figures of speech like Fuwa Minato and Yamagami Karuta, she simply starts to talk in a knee-jerk way.

Aside from anime and video games as previously stated, Rika also loves to watch a baseball game, which was influenced by her grandfather who used to take her to baseball games when she was younger; she has stated that is her favorite baseball team.

When a stream is starting she greets with "play ball", and when ending a stream she gives a farewell with "game set" (Japanese term for concluding a baseball game, equivalent to "that's a game" in English).
