Reaction:
After Focus Effects resolve: Resolve the duel only by comparing the value of the Personalities' duel stat as it was immediately before the challenge, plus the focused cards' base Focus Values.
(Ignore other effects which alter stats, Focus Values, or the duel's outcome before it is determined.)
The Double Chi keyword works as usual. If either Personality has not focused, each may focus an extra time, starting with the challenged Personality.
(These last two effects override previous effects which negated Double Chi or prevented either Personality from focusing.)
