Kuro's social media game is weird. Across their Twitter accounts for different languages (EN, JP and KR), the resolution of images can greatly differ. For this little official art, it's only on Twitter as GIFs and the audio is only to one ear. Sometimes an animated version of an art or a special art is only on certain platforms. That's not getting into their presence on other platforms which I'm opting to ignore for now.
I like this concept of Sensei and his favorite student-wife reproducing an OC daughter-character, rather than the precedent of copy/pasting the halo from mother to child. Maybe the baby started off with her mother's halo, and then it developed individuality on the final stages of pregnancy?
