A conflictingly, unproven belief that all of life's problems/obstacles can all be conquered/averted by simply believing in friendship, or the belief in others close to a particular individual or group of friends. A popular theme in both the official Yu-Gi-Oh franchise and the abridged series created by
LittleKuriboh.
Téa Gardner, who appears in both the franchise and
abridge series, is a strong advocate of this belief (though exaggerated far more in the abridged series).
