黄昏幻形者

About This Game
“I’ll become your ideal girlfriend. So... please, give me just one more chance.”
The girl standing before Hiroto Takenouchi is his ex-girlfriend, Chise Kawamoto—the very girl he broke up with only yesterday.
But the “Chise” before him is no longer the girl he once knew.
Calling herself “Eiko,” she reveals that she is a Shapeshifter—an inhuman creature capable of devouring living beings and assimilating their forms, allowing her to blend seamlessly into human society.
According to Eiko, however, the real Chise is still alive.
Although Chise has been absorbed into Eiko’s body, she has not been digested. Instead, Eiko is keeping her alive inside herself.
Then, Eiko makes Hiroto an unbelievable proposition.
“Let me be your girlfriend. Just for a little while.”
“If you agree, I’ll give Chise back to you.”
And so begins a relationship that was never meant to exist.

At first, Hiroto sees it as nothing more than a fake romance—the price he must pay to get Chise back.
But as the two begin spending more time together, he discovers something he never expected.
Eiko understands him better than Chise ever did.
She remembers his habits, recognizes his feelings, and stays by his side whenever he is exhausted.
Through the days they spend together, Hiroto slowly begins to rediscover emotions he thought he had long forgotten:
The thrill of falling for someone.
The warmth of being needed.
And the courage to trust another person again.
Yet the more genuine their relationship becomes, the harder it is to ignore one undeniable truth.
Eiko is not human.
She can imitate Chise’s appearance, her voice, and even her emotions.
But beneath everything she has borrowed...
Who is the real Eiko?
When their limited time together finally comes to an end and the real Chise is returned to him, Hiroto must confront two questions:
Who is the girl standing before him?
And who does he truly love?
A romance that began with a lie...
What kind of ending awaits them?
