The Cradle Of Nurtured Eggs

It's another ordinary day in the ordinary lives of Mari and Kotone when something extraordinary happens: the townspeople begin to collapse one after another before their very eyes and transform into horrific monsters! Somehow unaffected by the unknown phenomena, Mari is guided by an ethereal voice and gains the ability to transform into Lilium, a heroine with the power to face the monsters head-on and send them packing. However, saving her home won't be as simple as clobbering her former friends and neighbors... The reality is that the door to another world has opened, and miasma is pouring out through the cracks, turning the town she knows and loves into an unrecognizable hellscape. Only by venturing into the unknown and staging an invasion of her own can Mari hope to stymie the threat and protect all she holds dear.
 
And yet, there are still so many questions left unanswered. What's the truth behind the miasma and the terrifying monsters that roam the streets? How and why did the two worlds become connected in the first place? And perhaps most importantly, is there truly a way for Mari to reverse the damage that's already been done and reclaim her old life?

This is a romance visual novel about spending roughly 100 days living together with two mysterious “Egg Girls”
Your daily choices affect four emotions: Affection, Empathy, Comfort, and Tension.
Drawing closer is not the only option—sometimes, choosing to keep a little distance matters just as much.
Over time, those choices quietly shape the tone of conversations, facial expressions, distance between characters, story events, and ultimately, the ending itself.
Even the same words can feel completely different depending on the relationship you’ve built and the emotions of that day.
 
Yukino is awkward, quiet, and kind.
Rinne is cheerful, honest, and straightforward.
 
As you spend your days with them, watch their feelings shift little by little—and see how your relationship changes with them.
Rather than relying on dramatic twists, this story treasures the weight of time spent with someone, the quiet sway of unspoken feelings, and the lingering afterglow that remains after the ending.

Maki and Airi had been happily married for three years. However, due to Maki’s declining sexual function, they were unable to conceive a child. So, they decided to undergo a “treatment” they saw advertised.
