Background
On 23 April 2021, the names of the fifth generation of NIJISANJI KR members were revealed, as well as their Twitter accounts. On 27 April 2021, it was announced that the members would hold their debut streams on 30 April 2021. Seffyna was the first of the three to debut.
Fans and mascot
- Her fans are called "SeffyNite" (세피나이트, セフィナイト).
Relationships
- "Mianhada Pinaya" (미안하다 피나야), Seffyna, Ban Hada, and Song Mia. These three debuted together.
- "56S" - Seffyna, Ban Hada, and Na Sera.
- "Mawang-gun" (마왕군, Demon Lord Army), Seffyna, Yang Nari, Na Sera.
- "Many Money Company" (めにまにカンパニー), Seffyna, Sakura Ritsuki, Nara Haramaung, and Nagao Kei.
Trivia
- Color: white.
- Her name "Seffyna" is a combination of "Selene" and "ff."
- "Selene" is the goddess and the personification of the Moon in ancient Greek mythology and religion.
- "ff" derives from the music dynamic fortissimo, meaning "very loud."
- She is very close with her kouhai Na Sera; the two collabs very frequently, and also often appear together in large-scaled collabs.
- In January 2022, Korean donation site Toonation released a TTS (text-to-speech) message reader using Seffyna's voice; she uses a unique high pitch voice intended to be associated with her chibi form that she frequently draws on Twitter; due to the TTS's nature as an AI that reads the messages when donated, her chibi form has been nicknamed "Mechafyna" and conceived as a creature who eats golden "shiny and dazzling" coins since then.
- She often posts a short video featuring Mechafyna, with the one of the most famous videos, simply titled "MONEY SONG," becoming a "digital drug" video akin to Rosemi Lovelock's The Great Rosemi-sama Theme Song. Even some of her kouhais such as Shikinagi Akira and Maria Marionette are fan of it.
- In May 2022, during a Minecraft stream, Yorumi Rena accidentally called Seffyna a bee cosplayer, since then she has been joking nicknamed a "bee fairy" by some Japanese viewers.
- She shares character designer Yushika with Han Chiho.
