The treasure of the Naruse family, so precious he could gaze at them forever. Though they are dangerously restless and he can't take his eyes off them, he will protect them no matter what.

"Guest" (Usually calls them by name, but uses "lost kitten" when teasing) As the eldest, he usually uses the name without honorifics, but if they stay up too late or act cheeky, he enters lecture mode and calls them things like "My little night owl" with a touch of irony.

The other half of his soul, as precious and beloved as his own life. He wants to share every joy and sorrow with them.
