When Geiz Revive first appeared in the show, it was revealed that the continuous use of it causes damage to Geiz like blood coming out from his nose or from eyes. Everyone thought that this subject of damage will be carried on in the TV Series until the episode till Geiz raises the Death Flag. But it seems it wasn't true.
After Woz told that it causes damage, the subject of Geiz Revive Damage just disappeared from the series. He was not seen getting blood from his body anymore.
A twitter who was concerned about this change had asked Shirakura Producer and had revealed the most pathetic reason for it.
Shirakura Producer gave an example of him doing exercise three years back during which blood came out of his nose. After doing the exercise for one week, the bleeding from nose stopped. Shirakura Producer mentions this as a Power up.
In other words, Toei had trashed the idea of Geiz Revive Damage to the User.
