Komai Ume Ends Driving-Lesson Game Early After AI Sister Keeps Going the Wrong Way

VARIUM — Komai Ume, a Varium streamer, called off a driving-lesson game on Tuesday after more than two hours of trying to coach an AI-voiced younger sister through turns and parking. “I’m at my limit,” she told viewers as she shut the game down, saying she was sorry not to have cleared it.

Ume, who appeared as her 3D model, opened the stream late and said she had lost track of time before going live. She explained that she had installed the game in a hurry because its demo might end soon. The player speaks directions aloud and the character answers back. Ume designed the sister herself, giving her twin tails and a plain white top, and named her Azuki.

“I was planning to raise her gently, but it turned out to be impossible after all.” — Komai Ume, after ending the lesson

The lessons quickly stopped following Ume’s directions. Azuki drove when told to wait, backed up when told to go forward, and at one point stared out the back window when Ume asked her to look ahead. Ume’s instructions, such as moving 10 centimeters or crawling at 3 km/h, were often answered with a different move, and the course included explosive hazards that Ume said she had forgotten about. She repeatedly tried to slow things down and praised Azuki when she stopped on target. By about two and a half hours in, she announced the lesson was over, said goodbye, and left briefly for a break.

Chat tracked the mismatch throughout. After the stop, Ume reflected that she had been rougher with the character than she would be with a real person, because she knew it was an AI. She also said the full version was listed for January 2027 and that she would like to try it again then.

The rest of the four-hour stream was free talk, or *zatsudan*: Ume discussed a video of a flying car, television dramas and the ongoing hunt for a way to mark her fourth anniversary. She settled on shabu-shabu with potato-based shochu and beer, picked out a small hot pot during the stream, and read the night’s 26 paid messages. She closed by saying she would be back the next day for a stream tied to a sake release from Varium, which she expected to taste only a little.
