The Saga Continues!

[Hellfighter 17]

Write each person's spoken words, however brief, as a separate paragraph. Use commas to set off dialogue tags such as "she said" or "he explained." Closely related narrative prose can be included in a paragraph with dialogue. If one person's speech goes on for more than one paragraph, use quotation marks to open the speech and at the beginning--but not the end--of each new paragraph in the speech. To close the speech, use quotation marks at the end of the final paragraph.

Super Buu's right and it is not different styles, Broli, the other people who do that are just grammatically incorrect. Not saying you have to follow this, I'm just saying that it is, indeed, incorrect not to do so.
