Yuuto who had defeated some of his enemies tried to go and help his other friends who were having trouble defeating the enemies. Now he finds a little girl with ice abilities who is none other than Crysta in a nearby location. The girl was having a hard time against a fire elemental enemy.
But ....
Even though Yuuto's strength doesn't appear to have any flaws that could be called a weakness, Yuuto actually has them.
He has a weakness in the real world, namely... most likely if Yuuto's considerable ability is used continuously, then Yuuto's chances of returning will be even smaller.
Currently the real Yuuto is in a deplorable condition and some of his organ functions are starting to decline even though his heart is very weak when it beats.
Yuuto did not realize this.
