A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from the Wayback Machine (its copy), so posts it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.

When a face down Ninjutsu Personality would be flipped face up... discard all cards illegally attached to him.
If a Ninjutsu Personality is removed from play by Suitengu's Surge that is attached to him and flips face up when he's out of play must you discard all cards illegally attached to him including Surge?

No. "Preserving... all attachments" (Suitengu's Surge text).
