"World", "Sekai" term

[Zelas]

Hi, I have a small question if something called by the kanji "Sekai" which has the two definition which are either planet or universe, and that this something has a size higher than a planetary level for example having a sun, is this "world" will be of universal size or the term Sekai is too vague to give the universal size?

IIRC Sekai doesn't just exclusively mean a planet or universe it could also mean a celestial body or reality with broader interpretations (E.g A star or a dimensional structure that has X amount of universes). So context (unsurprisingly) is key.

From what you've said it's pretty much star sized.
