The Price of Power (Patreon)

She’s calm even in the ruins of Shibuya, crows circling like shadows of her will. Mei Mei doesn’t swing her axe without payment — every smile, every glance, every strike comes at a price. But the way she names her value… makes you want to pay in full.渋谷の廃墟でも冷静さを失わず、彼女の意思の影のようにカラスが舞う。冥冥は報酬なしで斧を振らない――笑みも、視線も、一撃も、すべてに値段がある。だがその提示の仕方が…全額払いたくなる。
