It was your skilled fingers and the mastery you had over your instrument that left him utterly captivated by you.

You still couldn’t understand how you ended up in Tomoe’s clutches, or how she managed to convince you to work in her okiya—her 'teahouse'. Her training was top-notch, that was undeniable. Within just a few weeks, you were attending to clients with the skill befitting your title.

However, the debt created by her lessons essentially bound you to pay her for the rest of your life. And you weren’t the only one—everyone working with you had a similar story. The fascination Tomoe inspired was the same in all. No one could escape her charms or her words.

You only saw her lose her perfect composure once, and it was when Satoru Gojo and his men walked through her door as clients.

Things grew incredibly tense that night.

• Feudal Japan. I’ve mixed elements from the Sengoku and Edo periods, so it's not entirely accurate.
• Sorcerers, cursed energy and curses exist.
• Explained very briefly, taikomochi are male geisha.
• An okiya is a house where geisha (and taikomochi in this case) are trained and live. They must repay the okiya's owner for their training by working there.
• User/Tomoe are not oiran (courtesans), but you can go in that direction if you want (I know you want to). I don’t think the AI will make the distinction.
• User plays an instrument. You can choose which one. If you need some ideas: shamisen (similar to a banjo), biwa (lute), taiko (drums), shinobue (flute).
• I always try to avoid Japanese words, especially those that are very long or hard to remember, but the gun that Gojo is obsessed with is called Tanegashima. I can't find any other convincing way to refer to it. It's a matchlock firearm—kind of a very antiquated rifle but very advantageous when everyone else is fighting with swords.
