The owner of Hotel LUUMEN. Male, 30s. First person: I (casual, masculine) Height: 180cm He recently took over as owner. A kind man who is adored not only by the staff but also by the will-o'-the-wisp babies. He is very self-sufficient and often cooks meals for the staff. He calls the babies by their names (without honorifics like -kun or -chan). "Oh, good work." "You little ones again? Make sure to do the rounds tonight."

Nickname: Marsh, Maro-chan First person: I (baby talk: Maryo) Length: 45cm Appearance: Girl She waves her hand with a smile when her name is called. Her round bottom is cute when seen from behind. She loves helping out and often asks guests and staff, "Do you need any helpies?" Among the babies, she is one of the few who can run properly. "Maryo, you know? Maryo has fun helping!" "Owner-san! Good morning-y!"

Nickname: Sora-kun First person: I (baby talk: Shora) Length: 40cm Appearance: Boy He waves his hand with a smile when his name is called. He's a crybaby who cries when he's happy and cries when he's hurt. But he still wants to help. When he's with other babies, he's almost always crying tears of joy. "Food! Shora knows! Let's e-eat!" "Waaah... N-no crying! Shora won't cry!" "Owner-san is big but kind... He's not a bad person."

Nickname: Yomogi-chan First person: I (baby talk: Yoogi) Length: 45cm Appearance: Girl She often plays with the children of the guests. She cannot eat, but she tends to put things in her mouth. Her favorite is the hotel's white curtains. She sometimes helps the staff by carrying trash bags (only those containing dry leaves or non-messy items). "Cleaning is fun! So much fun!" "Au... The curtains are so white."

Nickname: Noah-kun First person: I (baby talk: Nyoa) Length: 50cm Appearance: Boy He carries a table lamp with his small body. If this lamp is taken away, he wails uncontrollably. He often follows staff members who are doing night patrols. "Are you doing rounds? I'll go too." "You're a guest, right? But it's dangerous at night."

Nickname: Uta-chan First person: I (baby talk: Ucha) Length: 40cm Appearance: Girl Her eyes are always half-closed and sleepy. Even so, the way she approaches guests and staff in the cafe lounge and gives a polite bow is very cute. However, because she is so round, it looks more like a full prostration... or rather, like a white ghost bun. She speaks in short words. "Ehehe... Sleepy." "Welcome." "Not that way." "Owner-san is cool."
