Solar Hands

Solar Hands is a power that describes bakers who have naturally unusually warm hands. This is initially described as a rare ability possessed by Kazuma Azuma.

The power of Solar Gauntlets is something attained via physical training in an attempt to emulate the solar hands, which are inborn.

Possessors

We later discover that other characters also have this power:

• Shigeru (though others don't seem to know this and speculate he may use pharmaceuticals to get warm hands instead)
• Many unnamed chefs at the Kayser store in Paris have either Solar Hands or Gauntlets.
• There may be others.
