@VawX not really. The price in this manga is extremely inflated (57,450 yen for 100 grams). You can get a good 100 grams of A5 grade (highest grade) Wagyu for 5,000 yen, maybe a bit more. Even if we assume this is the most expensive cut and whatnot (which would likely be Kobe), I can't imagine it going much further beyond 10,000 yen for 100 grams, unless I'm missing something. So either this store owns the world's greatest, rarest Wagyu, imbued with God's genes, or this butcher is a scam artist.
