High-voltage coil for the laser (suspicious)
Artist's commentary
Hang in There, Kogasa-san 2108
I don't know the art of investigating which part is broken, so I held a round-robin of going through suspicious components. Except for the electrolytic condenser, none of them are sold in Akihabara, so I ultimately bought them online. I get the feeling Akihabara's no longer "the town with everything". Tomorrow, we see what happened with these parts!
