Article content should be organized in this way.
Talk about the character's past and main events that happened in their lives.
Talk about how they act. Their characteristics [Example: Witty, Outgoing, etc]. Try to compare these characteristic to things they've actually done in the series.
How they look like [Hair, Clothing, Distict features, etc]. The Anime and Manga can differ, make sure to include that variance.
What they've done in the series. This should be written as a synopsis. Keep the summary general and clear to understand.
It should be broken down into 2 subtopics:
Anime and Manga

Random facts or references. There's not much, but include if you found some.
