Mei Yasumura
Mei Yasumura (安村 メイ, Yasumura Mei?) is Misuzu's ganguro daughter, who hates her father for being a cross-dresser, as it was the reason her parents divorced and left her without a proper father figure for most of her childhood. Yasumura is her stepfather's surname, since Mei's custody was given to her mother after the divorce. She is a manga-only character.
Misuzu gets the Fujiokas to keep an eye on his daughter for a while, as she keeps running away from him and refuses to stay at his house. During her stay at the Fujiokas, Haruhi secretly prepares meals for Mei using Misuzu's recipes, such as jam and demiglace sauce, which Tamaki obtains from Misuzu by working part-time at the pension. Mei eventually sees through Tamaki's plan and reconciles with Misuzu by requesting some more of his cooking.
One of Mei's favourite hobbies is creating her own fashions and loves seeing her clothes on other girls. Mei is so dedicated to this hobby that she is willing to wake up early in the morning to sew a new dress and sometimes gets so carried away that her homework is neglected. When she discovers that the mother of Hikaru and Kaoru is the famous designer Yuzuha Hitachiin, Mei persuades Haruhi to accept an invite to the twins' mansion so Mei can meet her idol in person. Yuzuha lives up to Mei's expectations and together they try to photograph Haruhi wearing cute outfits designed by Yuzuha.
From the moment she saw Tamaki, Mei developed a crush on him and enlisted Haruhi's reluctant help to attract his attention. Later, she suspects that Tamaki might be in love with Haruhi and vice versa, and she is the first to notice Haruhi's feelings towards Tamaki. As they become better friends, Mei provides Haruhi with love advice, using a girls' magazine to help Haruhi understand her relationship with Tamaki; her assistance gives Tamaki an advantage over Hikaru in confessing his feelings to Haruhi.
In the volume 18 extras, Mei is shown at the beginning of her romantic relationship with Ritsu Kasanoda, informing him that Haruhi is pregnant, and commanding him to knit something for the baby.
A special chapter released in July 2011 in Lala revealed how she met Kasanoda: when she is a first-year fashion student at a women's college, the twins send Kasanoda to Mei as a replacement model for her fashion show (they were originally the ones who were going to model). She eventually becomes friends with him, even encouraging him at one point to make a move on Haruhi (whom she knows he still has a crush on) while Tamaki is in the United States by showing her his carpentry skills; her reason for doing so is that he should learn to be confident in himself and what he does. It is the fact that she needs him and needs his help, however, that eventually appeals to him the most, although no romantic relationship is formed at the time. It is implied that it takes a few years for them to finally date, since their occupations (Mei is a rising designer, Kasanoda a florist), rather than their student statuses, are listed in the volume 18 extra about their futures. Mei is the only non-Host Club member to appear on any volume cover of the manga.
