The Holy Grail War Blessed by the Gods

Having become the dead Manju, he was given a chance: he only needed to participate in and win seven Holy Grail Wars to be reborn.
He will join the Holy Grail War as a Servant with randomly acquired abilities and a blessing.
The blessing he received was obtained by invoking the name of the gods to gain their power and blessings.
Shouting the name of Zeus brings down thunder from the sky; invoking the holy name of Michael brings forth the great feat of slaying the dragon; the wisdom of the great god Odin blossoms in his name, revealing the mysteries of runes...
Under Ra's divine light, the Holy Grail was within reach.
