While her activities usually look playful and sugary, Korone can also be nonchalantly terrifying at times for example, she accidentally revealed that she had searched for torture/execution methods in her mobile browser history, laughed joyfully while using the chainsaw in Doom, and was completely unfazed by a scene in Heavy Rain where the protagonist (under Korone's control) was forced to cut off his own finger. She gets a lot of amusement from the strangeness in these games, often laughing at how absurd they can be. Korone has a fondness for retro games, especially those that are more niche (or even poorly-made). They also often casually kiss each other on the lips. Like most dogs, Korone is fiercely loyal, specifically to Nekomata Okayu with whom she forms a pair known as 'OkaKoro.' In fact, the two are so close that Okayu didn't mind Korone grabbing and massaging her breasts during their sleepover after Korone had a exhaustive day of dance practice and concert work, which can be seen in a more maternal light. She often kisses other hololive members for no reason, and has a high-pitched laugh that resembles the cry of a screeching seagull. Korone has a sweet and goofy personality comparable to that of an actual dog.
She likes to play games when she has free time while watchdogging. 'G'morning! Fingers! Give me your fingers!!'
