Long Long Man

Long Long Man is the tale of Chi-chan and her boyfriend Tooru-san who are huge fans of Sakeru Gummy, a line of “rippable” chewing gum that comes in both short and “looong” formats. The practical, down to earth Tooru-san prefers the smaller, more traditional size of gum. Unfortunately for him, however, Chi-chan’s desires are more unconventional.

The eleven episodes tell the tale of Chi-chan’s rapturous, rollercoaster love life. It begins on a carefree day in the park, where she and Tooru-san are enjoying short pieces of gum in the sunshine. That is, until she lays eyes on a mysteriously goateed and tuxedoed stranger called Loooong, Looooooong, Maaaaaaaaaan.

She is immediately transfixed by the length of his gum, and after he mysteriously appears both during another date with Tooru-san at the zoo (Long Long Man’s gum is as long as an elephant’s trunk!), then at her doorstep (delivering a box of Tooru-san’s boring short gum, with a stick of his long gum sticking out of his delivery uniform pocket), she can no longer resist, and throws herself (mouth first) into his smooth, gum-ripping arms. This of course means she must end things with Tooru-san, who is beside himself with grief. That is until Chi-chan dramatically claims she is dying, which is why “whenever she looks at long things, she feels assured.” No logical connection between death and long gum is ever offered.

Eventually she reconciles with Tooru-san after a friend with strong spatial awareness points out that  many short gums equal one long, long gum and agrees to marry him, despite being sexually haunted by elongated objects.
