soraru's real name is quite long (it got cut off nationwide mock exam), he had up to 10 cats at once at his family's house, he's stated that he chose his utaite name because he likes the open sky; the "sora" in Soraru meaning "sky". his real name also contains the kanji character for "sky" (空).
yukimura chose their name after the historical samurai general Sanada Yukimura, their real name is also yuuki lol. They had hawk moth caterpillars as pets and one of them grew into a butterfly, so they let it go. they also have a turtle and two cats, one of the cats are with their parents! me and yukimura are also in a committed relationship 🤞 (I'm being delusional)
