Is This Heroic Spirit a Fake?

The heroic spirit Savior, who accompanied humanity's last Master from the First Singularity all the way to the end, suddenly disappeared from Chaldea one day. And so... the original inhabitants of other worlds became her victims. After losing her source of magical energy, the heroic spirit girl had no choice but to force others to replenish her mana so she could barely remain in the present world. Known victims include: the No. 4 Pro Hero, a certain bandage-wasting device, a certain nine-tailed fox, a certain Pillar, a certain Five-Yen God, a certain endlessly dividing worm-man, and a certain leader made of black sludge. 1v1.
