Grok imagine prompt: Realistic cartoon style video of Hachiko’s true 1920s Tokyo life: the Akita puppy born in 1923 in Ōdate, adopted by Professor Ueno in 1924, their daily walks to Shibuya Station, Ueno’s sudden death in 1925 from cerebral haemorrhage, and Hachiko’s real, faithful wait every day for nearly 10 years until his passing in 1935 amid crowds and seasons.
