Bayonetta entering Serious Mode before her fight against Fortitudo.
The ability is only activated at certain points in the story of Bayonetta, primarily before a battle against the Auditio. Unlike Umbran Climax, the player is not able to manually activate Serious Mode, and it does not deplete the Magic Gauge.
Serious Mode is an ability exclusive to the Umbra Witches, with both Bayonetta and Jeanne being able to enable it before combating a tough enemy. If Bayonetta is equipped with Scarborough Fair (or Jeanne with All 4 One) it allows for every punch and kick attack to be accompanied by a powerful Wicked Weave. If either character is equipped with any other weapon, a powered-up version of it accompanies the regular attack. Due to the limited playable characters in the first game, it is unknown if the Lumen Sages or Rodin possess this ability.
Serious Mode performs the exact same functions for both Bayonetta and Jeanne in the original game. As in normal gameplay, if a combo is performed in Serious Mode, the finisher attack will be the most powerful.
Equipping the Climax Brace will allow both characters to use Serious Mode during any Chapter, however, it will not save any records. Entering Serious Mode is usually seen during cutscenes, and it is signaled by either witch letting down a large portion of their hair. The chains on the Umbran uniform are also woven into the hair when in Serious Mode.
