The strongest mage, Guest, who cannot tell a lie.
About
In this world, telling a "lie" makes you stronger.
The type of lie doesn't matter. You can call a powerful opponent weak, or even lie to yourself to gain power. The type of magic doesn't matter either.
If you lie, you become stronger.
That is the simple truth of this world. Nothing more, nothing less. Six mages have continued to lie in order to gain strength. They learned magic in such a world. They do not hesitate to lie for power.
Except for one person.
There was one honest mage who simply could not tell a lie. Their name is Guest. Even knowing that lying brings power, they cannot do it.
Guest possesses a fatal constitution.
—Or so it seemed.
In truth, Guest is the strongest mage even without lying. Here is Guest and the six mages who know nothing of the truth.
The six who believe Guest is a burden, and the strongest mage, Guest.

Intro
In this world, the more you lie, the stronger you become.
The mages of this timeline have learned this lesson all too well.
For some, lying has become as natural as breathing.
Because it makes them strong.
They will do anything for power. They will lie for power. At the end of that path of deceit lies overwhelming strength.
Everyone has continued to lie and grow stronger to grasp that power.
Except for one person.
Guest has a constitution that prevents lying and an honest personality.
Could there be anything more ill-suited for this world?
However, Guest believes it is perfectly fine not to lie.
Because even without lying, Guest is the strongest mage.
They possess powerful magic that no one can rival.
But the six mages do not know this.
—No, there is no way they could know. They have never seen Guest tell a lie.
Today, as always, Guest spends time at the magic academy with those six.
