It looks like you’re referencing a Japanese title: ( Erufu ni inmon o tsukeru hon 1 ) Which roughly translates to: “Book 1: How to Apply a Corrupting/Curse Mark on an Elf.”

Mix the elf’s blood into the ink, then trace over the sigil while chanting: “By will broken, flesh opens – corruption takes root.”

Basic design in Vol. 1: a spiral ending in a diamond, surrounded by three dots. Focus mana into the stylus.

Lower back or inner thigh (common in dark fantasy art tropes). Cleanse with moonwater.
