☆Summary
It's a day in summer holiday.
You recently started living alone in the city, and are beginning to get worn out by the busy days.
Noises of the town, complicated relationship with others... Momentarily, your heart yearned for a moment of peaceful rest in a quiet place

It made you recall your time back when you live on a small island.
Surrounded by nature, living a free life, the time of serenity...

Led by the nostalgia, you made a phone call to an old lady running a guesthouse at the island.

What came back was a cheerful welcome along with an unexpected favor.
「Our daughters will be on their own for a while, can you look after them?」

This marks the start of the 14 days of your summer break.
The beginning of special days with two girls in a nostalgic island.

☆Character Introduction

Honoka Amane

The elder sister of your childhood friends.
She's kind and gentle.
She's been helping out the guesthouse since young and is good at cooking.
She looks matured to others around her, but she can be spacey at times.

After not meeting for a while, she sees you grown up to be so manly,
an gets nervous deep inside.

Hinano Amane

The younger sister of your childhood friends.
She rarely shows her expressions, and is sometimes absent-minded,
but she's been helping her dad in shipwright and has skillful hands.
She loves odd things, and sometimes brings back something from abandoned buildings.

Her face doesn't show it, but she's happy to get to meet you again.

☆H Scenes

Once they're comfortable, you can go to remote places... and your secret time with them begins.
And eventually, they will be willing to do you a "favor" anytime, anywhere...

☆About This Game
"Hospitality"... That is one of the most important study subject for angels, who will be guiding humans and providing them assistance in the future.
How-e-ver! This lazy, sluggish angel apprentice Mika over here has been skipping those lessons, so much she's in the verge of getting retained from promotion!
At this rate, she's going to be an angel apprentice for life...!?
To break the status quo, Goddess Freya gave orders to Mika and her angel apprentice friends, Bel and Az, to descend down to human land. Collect "Love" to avoid retention.
In a desert town full of mysteries, our Angel Apprentice Mika shall demonstrate her outstanding performance!
...or, maybe not...!

☆Character Introduction

★Michael (Mika)
A downer, lazy angel apprentice who is also the protagonist of this game.
She skipped too many "Hospitality" lessons - a lesson for angels to help humans - and ended up having to descend to human land for make-up lessons...

★Belzebuth (Bel)
A not-so-sharp, energetic angel apprentice.
She just can't get along with Mika, and they fight literally every time they encounter each other.
She's too dull to get any credit on Hospitality, and is forced to take make-up lessons with Mika.
However, bad thugs know a way or two around her ignorance...

★Azrael (Az)
A somewhat cold, excellent role model-like angel, who is Mika and Bel's junior.
She is almost flawless, with the only flaw being her arrogance.
Goddess Freya gave her a mission to look after her underachieved seniors, and communicate with humans to soften her attitude while she's at it.
But of course, Az is so full of pride, and that doesn't exactly make things easy...

★Freya
A kind-hearted goddess who looks after Mika and others.
She always wears a gentle smile like a goddess.
She occasionally descends down to land to check up on Mika and the rest.

☆Game System

Humans don't just open up their minds that easily.

Use the power of the angels to initiate multiple-choice quiz mini-game.
Within a time limit, pick the right answer out among the four choices to earn their trusts and gain some "Love"!
Quizzes range from general knowledge to in-game context!
When you find it difficult, there are also assist items that can help you find the correct answer!

Help Mika avoid retention by clearing quizzes and solve people's problems!

☆A Variety of Dress Up Costumes!

There is a large variety of costumes and accessories!
Hair color, hairstyle, even skin color!
Ranging from simple cute and adorable to all kinds of fetishes!
Combine your favorite accessories for your own original Mika!

Costumes also affects Mika's appearance in sidescrolling view indoors!
