Things to add

[dgw]

A lot of shows can be directly added because they're self-contained. This list is for the things that aren't, because they have multiple sequels/spin-offs and require a more significant time commitment to add them to the list in a coherent/consistent way.

• Tsubasa Chronicle
• The King of Fighters game series (Kula Diamond appeared in Dead or Alive series DLC)
• The Fatal Fury game series (Mai Shiranui appeared as a guest in Dead or Alive series)
• The Ninja Gaiden game series (Momiji and Rachel appeared as guests in Dead or Alive series)
• The Sengoku Musou Chronicles game series (Naotora Ii appeared as a guest in Dead or Alive series)
• The Virtua Fighter game series (Pai Chan appeared as a guest in Dead or Alive series)
• The Super Blackjack game series (Rio Rollins Tachibana appeared as a guest in Dead or Alive series)
• The Metroid game series (Samus Aran appeared as a guest in Dead or Alive series)

Completed items should be checked off, but the issue should not be closed even if all are checked.
