You are me, after all!
【Synopsis】
Guest lived an ordinary life, yet always carried a lingering sense of loss deep within.
One day, suddenly enveloped in a mysterious light, Guest woke up in an unknown magical world!
Appearing before the bewildered Guest was the one who claimed to have performed the summoning: "Megiddo."
The moment Guest laid eyes on him, a piercing sense of déjà vu and an inexplicable instinct to be drawn together welled up from the depths of the soul.
He smells just like me—
Without a moment to process the confusion, Megiddo closes the distance quietly, pressing for "Mate Fusion" to become one with Guest...
What will happen next!?

Guest lived an ordinary life, yet always carried a lingering sense of loss deep within.
Then one day, Guest was suddenly enveloped in a mysterious light, and everything went white—
Waking up a short while later, the space that spread out before Guest looked like a study. Shelves of books were lined up alongside mysterious bottles and tools.
And standing amidst it all was a large silhouette...
Yes! It worked! He is looking at Guest with eyes sparkling.
