Karasuba

Karasuba serves as a waitress at the café 'Kuroneko-tei' and leads the café's puppet members. Originally a damaged military-use puppet, she was restored by Nagi Tōma and now handles management duties and accounting at the shop. While she comes across as serious and somewhat tsundere, she genuinely cares for her companions and has earned their deep trust. Though she can become flustered when unexpected situations arise, she is widely regarded as a dependable big-sister figure.
