"A green woman from the neighboring country, a maid with a beautiful singing voice. In early fanworks she was often mistakenly portrayed as a princess. She is a spirit from the Millennium Forest who took human form to help Elluka Clockworker in her quest for retrieve the Vessels of Sin. She's a close friend of Gumillia. She takes the form of a blue robin in spirit form, and made her human form based on Eve Moonlit after witnessing the events of moonlit bear.
In the second period, she was known as Lich Arklow's younger brother Michael and was one of Levia barisol's assistants. Michael Arklow was misread by Held Yggdra as "Michaela", leading to her gaining it as a nickname. She was engaged to Levia's other assistant Gumillia Matsumoto. Since she regained her memories of the Second Period and still chose to appear in her female form after the end of the world, she is considered to be a transgender woman.
After being found by the outcast Clarith, both girls grew close and eventually arrived to Aceid, the capital city of Elphegort, where they were hired by Freezis family, eventually meeting the King Kyle Marlon. This fateful encounter led to the invasion Lucifenia against Elphegort, in which she was killed by "a golden haired assassin". This is implied to be Allen Avadonia, but is actually Ney Phutapie.
After her death, she was reincarnated as a tree and was chosen to succeed Held as the new Deity of the Millennium Forest.
