- If you were looking for the character with the Japanese name of Mirei, see Rui.
Mirei first appears in Absolutely Azumarill. She is first seen at Route 42, chasing after a runaway wild Azumarill. After the Azumarill escapes, Mirei encounters Crystal, who she asks to capture the Azumarill. To Mirei's shock, Crystal is unable to catch the Azumarill before it runs away.
Crystal explains that she was defeated by a powerful Pokémon she tried to catch. The shock caused by the incident made Crystal unable to capture any Pokémon. Mirei slaps Crystal to get her to stop crying and tells her daughter that she must complete the task of completing the Pokédex given to her by Professor Oak. After Crystal calms down, Mirei tells her that she must start from scratch and train at Mt. Mortar, where Crystal first learned how to use her capture skills.
In Fortunately for Feraligatr, Mirei takes Crystal to the Safari Zone via a helicopter. To Mirei's disappointment, she finds Crystal in professional work attire for her field trip with the children from Earl Dervish's Pokémon academy. Believing the trip should be fun for the children, Mirei forcibly picks a new set of clothes for Crystal, much to the latter's dismay.
