曾孫のセワシです!
I'm Sewashi Nobi, your great-great-grandson!
— Sewashi Nobi to Nobita Nobi, All the Way From the Country of the Future
Sewashi Nobi (野比セワシ Nobi Sewashi) is the great-great-grandson of Nobita Nobi and Shizuka Minamoto. Sewashi was the first owner of Doraemon. He sent Doraemon back to the past to help and take care Nobita in order to get a better future of his life.
Appearance
Sewashi's overall appearance is very similar to Nobisuke, Nobita's son, having fair skin, black hair and big black eyes. In Stand by Me Doraemon, however, his hair is ginger in colour.
In the 1973 anime, he wore a red and white jumpsuit. He also wore glasses like Nobita, but they were removed in the subsequent anime series. In the 1979 anime, he wore a teal and white shirt, long white pants with a red belt as well as teal boots. He wears a jumpsuit with a turtleneck shirt underneath in the 2005 anime and Stand by Me Doraemon, although the color schemes are different.
Personality
Sewashi, like his ancestors, does not perform well in school, but is otherwise quite athletic. He is also helpful on occasions, having sent Doraemon and Dorami to help his ancestor, Nobita. Like Nobita, he is afraid of dentists.
Family
Not much is known about Sewashi's family than his great-great-grandparents, Nobita and Shizuka.
Sewashi's mother is only shown once, and resembles Nobita's mother, but more futuristic, a bit nicer and wears no glasses. Sewashi's father, who is Nobita and Shizuka's great-grandson, has appeared in the series a few times (in the short movie, 2112: The Birth of Doraemon).
It is known that Nobisuke (Shizuka and Nobita's son) is his great-grandfather and that Nobita's parents are his great-great-great-grandparents.
Trivia
- In the 1973 anime, Sewashi wears glasses and red clothes (which he almost looked like Nobita), which was changed in 1979 and 2005 anime.
- In the official English manga and anime, Sewashi Nobi is renamed to Soby Nobi.
- In the 2014 movie, Stand by Me Doraemon, his hair color is changed to ginger like in the manga and his clothes are re-colored.
- Fans often speculated that Sewashi had fabricated the photo album that he shown to Nobita in the first chapter, as changing the past is generally considered risky, and Doraemon's prediction the photo of Nobita in full body cast was unchanged when the timeline was altered. Even though Sewashi says that Doraemon's interference will not alter his own birth and therefore his existence is unaffected, it should be noted that Sewashi would still end up with a different life with different ancestors, so it's likely that he only sends Doraemon back in time to complete the causal loop.
- Sewashi comes from the 22nd Century in 1979 and 2005 Anime. But he came from the 21st century in the 1973 Anime which suggested that he is Nobita's son or Nobita's grandson or Nobita's great grandson.
- In the Indian dub, it is shown that Sewashi is Nobita's grandson, not him. But Nobita is often irritated when Sewashi calls him Grandpa. So, he responds back by saying, "Don't call me Grandpa!'
