Haruhiko Kanna is just an ordinary man with an ordinary life. One day he meets 3 witches in a small room in the old clock tower, and that's when his ordinary life became not so ordinary at all.
With the curse, or gift, he was granted that he'll change to a girl once the clock strikes 12 Noon, and will return to his male self at 12 Midnight. He then asks himself, "What on earth will happen if this goes on? Can I survive like this? Most of all will I turn back to normal again?!"

Naoto Saki is a typical young boy. He gets average grades in school, and nothing about him really stands out. His favorite thing to do is sleep - which doesn't exactly endear him to his teachers when he dozes off in class. Whenever he falls asleep, Naoto dreams of the same fantasy world. Then one day, Naoto gets magically summoned into the very world he had once only seen in dreams! All at once, he's caught up in a battle between the powerful beings called Elphis, and a group of human-like beings called the Sand Dusts. For Naoto, this desert world of Orgos is no longer a dream-he can feel pain here, and possibly even die. He decides he'd rather not risk his life, and would like nothing more than to return home. But the pretty sorceress who summoned him in the first place has other plans for him.

“Alcafus” is a story about a mysterious Kemonomimi creature the MC, Tadashi met during his childhood one day. He had discovered that a girl with ears and a tail like a beast was falling down at a shrine, when checking if she was uninjured he gave her a candy ball that she seemed to really enjoy. After being pestered for a second one he gave her one and she repaid him with a kiss, soon after she disappeared. Ten years have passed since then, and when he heard her voice calling him, Tadashi visited the memorable shrine and strayed into a mysterious world.
