Blade: yknow that one moment in Lilo and Stitch when Lilo puts Stitch'es claw over a vinyl record and opens his mouth and the music from the record plays through it? Blade can do that
Garu: he got into storytelling illustration after seeing Olivine's handmade books he makes with his own stories (idk if it's confirmed or not but I want to believe)
Eiden: despite being nosy, he actually would prefer not run into Aster's staff being close and personal with each other but Somehow he always walks onto people and constantly has to backtrack while sputtering and wondering Why he happens to walk onto Aster's workers more than on his own boys
Karu: Rei let's him join into his experiments that includes explosives and because of Karu's enthusiasm Rei also ends up just quietly cackling while setting up another experimental bomb. He makes some with colorful sparks like its a firework specifically for Karu to marvel at 🎆
