Mercurius

Mercury is the sixth and final goddess to be introduced and is the youngest of the Jupiter Sisters, who is confirmed to reside within Ayumi.

Mercury has a very detached personality that can sometimes be misunderstood as absolute indifference. Her personality is sometimes misunderstood because she tends to deal with the problems of others as if they are trivial things not worthy of her attention, even if said problems affect her as well. Mercury is not completely devoid of emotion, however, since she does worry about Ayumi whenever Ayumi feels troubled and even immediately apologizes if she faces admonishment, providing that she understands that she is initially at fault.
