Puppy-sensei

xs is a friendly and sometimes pretty goofy vtuber with a definite "teacher" vibe. She really cares about her students, about their learning, and about promoting interest in the Japanese language and culture.

Puppy-sensei has a bit of a punk teacher vibe. She wears a hoodie and has vibrant, sea-blue colored eyes. She has floppy puppy ears that droop from the top of her head and is always seen smiling. She wears a choker on her neck with a trading pendant that was recovered from a Dutch merchant vessel off the sea of Japan.

In fall, 2025, She unveiled a new outfit which she refers to as her "librarian phase". The outfit is a conservative vested top with a skirt, often accompanied with a beret.

Prior to her debut with IRIAM, she wore a pink collar with a bell and rounded glasses.

• Puppy-sensei's ancestors were brought to Japan by Dutch trading vessels.
• She used to be the classroom pet in a different teacher's classroom, and that she really enjoyed getting to help out the students in return for treats and headpats. After a while she earned the teacher's respect and began to train to become a teacher herself.
• She was originally found in a box, and no one is quite sure where she came from originally.

• She once lived in China. Currently she works with Manager-sama who edits (and occasionally appears in) her videos.
• She claims she was actually learning Chinese before she ever considered trying to learn Japanese, but decided to switch to Japanese after going to school in Shanghai.
