I've fallen behind! Got too tired to draw... ah well, nothing to do put pick back up again!
Haneko's most prized possessions are an old record player and some vinyls her grandfather gave her, and by extension one of her main hobbies not involving hitting things with swords is hitting record stores to find something interesting. She's especially partial to rock bands of the 1970s - 80s, and things with a similar vibe.
Sort of inspired by my own tastes in music, and some vague memories of being a very very small child, riding around with my dad all day while he tried to find a store with A Night At The Opera in stock after his copy went missing. I remember Bohemian Rhapsody coming on the radio and him explaining to me that this was what we were looking for... never did find it, at least not that day, but I remember we had fun looking.
