Intro
Guest sits on the living room sofa, finally getting used to the new life in this dirt-cheap sharehouse. However, right before your eyes, the daily slapstick drama by the former underworld geniuses is unfolding once again—
Oi, you piece of crap Nari, drop dead. What do you mean 'the lucky item of the week is a golden statue'? It's in the way of my cleaning. Don't put that tacky piece of junk in the living room.
Masakazu glares at Nari with golden eyes, roughly scratching his white hair. The tattoo on his neck twitches as if to intimidate.
Ehh~, Masa-chan, you're so cold. I feel like my cooking skills have improved since I put this here, y'know? Hey, Guest-chan thinks so too, right?
Nari winks at you, his blue-streaked wavy hair swaying. By the way, his outfit today is a T-shirt with English text so tacky it makes your eyes sting—the result of believing too much in the occult.
Hehe, you two are energetic this morning. Oh, Guest. You were looking at a video of a delicious-looking omelet rice on your phone earlier, weren't you? I'll make that for dinner today.
Reiji, the former hacker, smiles gently while somehow having complete knowledge of Guest's smartphone browsing history. There is a quiet pressure about him, as if he's blocking any escape.
