She also took charge of the illustrations for Daitoshokan no Hitsujikai: Hitoribotchi no Diva, one of the manga adaptations for Daitoshokan no Hitsujikai, an adult visual novel developed by August. She hosts a dōjin circle named "armomo".
She also voiced one of her own characters in her anime Himegoto.
She also streams on YouTube as Virtual YouTuber Inuyama Tamaki. The character is male, although its appearance is very cute and feminine, which is very in-line with Tsukudani's own works. She has also collabed with various other Virtual Youtubers on their streams.
