## Description
Doumoto Takaya was bored.

One evening, he had taken up his childhood friend’s invitation to have a late-night picnic. He accepted, if only to subdue his boredom, and was encouraged to wish upon the shooting stars that were a common spectacle in the town of Hoshigino. During their picnic, a shooting star whisked across the sky and he hurriedly wished for “something fun and wondrous” to occur in his seemingly boring life.

To their surprise, stars began to trickle down from the sky and quickly turned into a full-fledged meteor shower. Rather than disappearing, the shooting stars seemed to have taken shape, aimed at Hoshigino, and enveloped it in a warm, bright light. Once the light dissipated, a single shooting star remained and barreled across the sky before ramming straight into the empty, nearby hill.

From the cloud of dust, Takaya and his chilldhood friend, Yua, discovered a rabbit-eared girl with white hair running straight for the town. Yua quickly chased after her, but rather than finding the rabbit-eared girl, they found something beyond their wildest imaginations...

### Arisu Yua (有栖 結愛)
Yua is the childhood friend of Takaya. It’s pretty obvious that this girl is already infatuated to the protagonist from the very beginning of the title; shown by her constant approaches despite the fact Takaya seems to find it annoying. Excellent at cooking and housework, Yua is ranked #1 in their school of the “Most wanted as a bride”. This kind of character is the type that makes other male students cry in hatred and frustration.

Despite her continuous approaches, Takaya originally sees Yua as nothing more than a childhood friend, as her fairytales were quite irrational and, perhaps to the cynical protagonist, annoying. Despite this, Takaya seems to enjoy Yua’s company because she’s the only real friend that he has… That is until the incident.

### Kokoro Judith (ココロ ユーディット)
The girl who emerged from the castle that the school was turned into after the meteor show. Kokoro is always accompanied by a maid named “Iru”, who can launch her head at anyone; this is done first at Takaya, but used often as a running gag against Adam when he steps out of his bounds.

It is revealed very early that Kokoro is a princess of a kingdom. It is not specified which kingdom she came from, or what kind of authority she holds. Despite this, after her house (castle) lands on the school, effectively replacing it, Kokoro takes the role of the school principal. This replaces the old principal, who happily retires into gardening strange flowers he seems to be able to talk to.

Kokoro may be a princess, but she’s very shy when it comes to Takaya, which suggests that the two may have met before. Her first words to the class is an arrogant statement that she “…will take anyone to become my servant!!”, but this was actually her plea to ask for friends; she simply didn’t know how to ask for friends directly.

### Yukishiro Miu (雪白 みう)
Miu is a mysterious girl who appeared on the day the shooting star hit the school. The first encounter with this character is when her house drops (along with a loud crash presumed to be a meteor), in the forest near the hill where the two childhood friend is stargazing at. She mutters the words “It’s definitely here…” and disappears, and soon reappears at the school - to meet the protagonist for the second time.

Miu’s personality is introverted and shy, but when it comes to sexuality, her identity as a “rabbit” is corresponding to the common statement “reproducing like rabbits”. Whenever she panics, her rabbit ears come out.
