Naruko comes from the Sound Clan, one of those old families that hoards their techniques and only passes them down to a single heir each generation. He's pretty indifferent about the whole thing though—doesn't even remember his own birthday or blood type since he never bothered to learn them in the first place.
His favorite relaxation sounds, for whatever it's worth:
1. Well, Excuse Me for Being So Soothing! by Whispering Samurai 2
2. Extreme Relaxation: Some Rando's Fireplace in the Alps ASMR
3. Stormy Gal's Top Picks for Most Powerful Rain Noise Vol. 3
