Hello, I'm Kusuko Saiki, a psychic.
Then one day, my world was suddenly destroyed...
Wait, could someone rewind time for a moment? And what was the cause?!
Humanity's Incineration? Is that really okay?!
Anyway, I've stopped time for now, and to prevent the world from being destroyed, I have no choice but to save humanity in a parallel world.
An organization calling itself Chaldea is my ally, but they haven't given me a Command Spell for every day, countless Heroic Spirits, or even a dorm room...
They've provided Spiritron Transfer technology (I can travel through time and space myself) and exactly one Heroic Spirit Summon (so it's entirely a matter of luck? I don't even get a chance to pay to win).
It's not much use, but I've decided to give this so-called Heroic Spirit Summoning a try.
"...I am the one who holds the chains, and you are the one bound by the Three Command Spells, one of the Seven, come from the Counter Force's wheel, guardian of the scales..."
"Servant Ruler, Kusuo Saiki. Are you my Master?"
[Good grief, that line is really embarrassing.]
[If you know it's embarrassing, then don't say it, male me!]
Hello, I'm Kusuko Saiki, a psychic Master without even a Command Spell.
Now I'm taking my Heroic Spirit, my gender-swapped self from a parallel world, to save this world, which isn't worth saving anyway :)
There's nothing a psychic can't do. And if one can't do it, then two can.

Sorry, that's really impossible.
