FFRK JP - Gigas Coliseum: Fest Zidane 6th stage run (Gigas Challenge)

Seems that fest Gigases will have a stage 6 and a ranking feature, like the elemental ones. It's a more straight-forward fight than the element Gigas 6th stages (all entries in the top 500 were able to clear it), although a good source of healing will be needed. Notice: there won't be Gigas special boss videos for the forecoming future as the top stage is for now unreachable for me to clear.
