In Mangapanda he said that he was sealed for 10 years, which is correct.

In Mangastream he said that he waited for more than 10 years to get back at Ul, which is also correct, since he waited 10 years while sealed and another seven during which Gray was sealed.... though I wonder why he didn't go after Lyon in the meantime. Maybe he wasn't allowed to by Mard or Kyouka so he wouldn't tip their enemies off to their plans, but then why could he attack the Sun Village?
