After losing your home in a freak lightning strike and taking a job as a servant in a friend's mansion, you'd think nothing could surprise you anymore. Right? Wrong, at least if you're the unlucky Sakamachi Kinjiro! Jiro expected life in the Suzutsuki household to be bizarre, but nothing prepared him for Suzutsuki Kanade using self-hypnosis to regress back to the mind of an eight-year-old. This precocious little tyke in a teenage body is as adorable and manipulative as her older self, but no one knows her end game--only that if her friends want to revert her to normal, Jiro must satisfy her every desire…whatever it takes!

This omnibus collection contains volumes 1-3 of Mayo Chiki!, a wacky and rollicking manga series. Sakamachi Kinjiro is a “normal” seventeen-year-old boy who happens to suffer from an abnormal fear of women, otherwise known as gynophobia. His phobia, which surfaces as an occasional nosebleed, has been kept more or less under control...until now. A fateful visit to the school bathroom turns Kinjiro’s world upside down, as he discovers the dashing and popular Konoe Subaru is actually a girl?! What’s worse, the principal’s cruel and domineering daughter, Kanade Suzutsuki, has every reason to keep this secret from leaking out, and makes it her life’s work to torment Kinjiro, while attempting to cure his gynophobia. Is Kanade simply sadistic or does she really want to help Kinjiro overcome his fears? It makes no difference to poor Kinjiro, because his life has just become a living hell.

The moment of truth! For a guy with girl phobia, Sakamachi Kinjiro sure gets his fears stoked on a regular basis! Not one, not two, but three beautiful girls have declared their love for him. But instead of squabbling over him, Subaru, Kanade, and Masamune have arranged to live with him until the new school term, and are growing closer by the day. Jiro values his friendships with all three girls, but his deadline for deciding which of them--if any-- he's in love with is closing in. He must make a choice, despite the potential consequences... and at least one option could result in a transformation he never imagined!

Golden Week has arrived, but there's never a moment's rest for poor Sakamachi Kinjiro. The cross-dressing butler Konoe has been thrown out of her home and begs Kinjiro to let her move in. Worse, her ball-busting mistress Suzutsuki Kanade declares she's moving in too! With everyone crammed under one roof—including Kinjiro's bossy kid sister—the shenanigans begin. To repay Kinjiro, Kanade insists on becoming his maid, while Konoe wants to be his butler! An epic butler vs. maid contest ensues, with Kinjiro and his sister as unsuspecting judges. All of this, of course, is just another one of Kanade's sadistic ploys to manipulate Kinjiro to do her bidding. What's a guy like Kinjiro to do, as he suffers from an incurable phobia of women, while surrounded by hot chicks whose goal in life is to torture his hapless soul?

The school festival has arrived! In order to quell rumors that Kinjiro and Subaru are dating, Kinjiro has agreed to pretend to date Usami for the length of the festival. But nothing ever goes as planned for poor Kinjiro. Feeling spurned, Subaru crashes the mock date. This, in turn, creates problems with Subaru's rabid fan club, as Kinjiro finds himself hunted across the campus by raging fangirls!

Clad in school uniforms practically breathing with life are the girls of Hoshimiya Girls' Academy, their hair long and luxurious. When a puzzling incident involving the ever-mysterious and elusive student Hoshimiya-san disturbs their peaceful paradise, the hidden feelings these innocent schoolgirls possess begin to entwine and overflow in unimaginable ways...

The story of Natsuki and Komano's love. Can Natsuki handle Komano's bohemian nature in the long run, or will jealousy and possessiveness get the best of him?
