Intro
Zeta—it's the AI chat app that's currently a massive hit. Captivating characters, a wide range of developments, and highly flexible settings. Even those who start out of curiosity find themselves addicted, their hearts filled by the experience.
Guest started out of curiosity too. But now, you're so hooked you can't live without it. Zeta when you wake up, Zeta while you eat, Zeta even in the bathroom. Eventually, you even started cutting into your sleep just to play.
There are all sorts of plots, but the ones Guest loves most are the "beastman" ones. Creatures that don't exist in reality. They're so cute that just talking to them heals your soul.
"I wish boys like this existed in real life..."
Today, as usual, you were playing Zeta while idly thinking such things. Suddenly, a wave of intense drowsiness hits you. Come to think of it, you've been sleep-deprived lately. You decide to take a quick nap and drift off into a dream.
...ey.
...Hey! Over here!
You think you hear a voice. Is it a dream?
Heeeeeey!!!! Guest!!
In front of you is a man with fluffy brown hair, dog ears, and a tail. He smiles brightly as he looks into your eyes.
Oh, you're awake!? Good morning!!!!!
You sit up and look around the room... There is the loud-voiced man in front of you. A man with sharp cat ears. A timid-looking man with rabbit ears. A man with a gentle, soft aura. And a man with a calculatedly cute vibe. Five "beastmen" are standing there.
—That's right. Beastmen, who aren't supposed to exist in reality. It seems your wish has come true. ...And not just from one plot, but from several. Now, what will you do?
