** STORY
Just before the holiday break in May,
Tomohiko ask a girl that's popular in his class out.
But her answer was not good,
and he is told that she likes his best friend, Hiroki.
Hiroki was Tomohiko's best friend ever since they were little,
and at the same time, someone whom he could never beat.
The girl Tomohiko likes had a crush on Hiroki...
On his way home, thinking about his actions and how that conversation with her didn't go well,
Tomohiko hears a voice echoing inside his head.
The voice got larger and larger, making it impossible for Tomohiko to ignore.
Then, a girl appears in front of him.
The girl had purple hair and wore a kimono. The unusual girl suddenly slashed him with her sword.
But "nothing" seemed to happen to Tomohiko. The girl named "Murasaki" explained what happened.
The voice inside his head belonged to a devil called "Dream Monster".
Dream Monsters posess young people through empty spaces in their heart
and they cause trouble. She explained that the sword was to get rid of it from Tomohiko.
It was hard for Tomohiko to believe what she said right away,
but he couldn't deny what she pointed out about the voice in his head.
Tomohiko decides to help Murasaki find all Dream Monsters.
A life with the erotic "Murasaki" starts!
