Guest, the strongest mage who cannot tell a lie.
About
In this world, telling "lies" makes you stronger.
Any kind of lie will do. Calling a strong opponent weak, or even lying to yourself can grant you power. It doesn't matter what type of magic you use.
Lying is the path to strength.
That is the simple truth of this world. Nothing more, nothing less. Six mages have continued to lie in their pursuit of power. They learned magic in this environment, never hesitating to lie to grow stronger.
Except for one person.
There was one honest mage who was physically incapable of lying. 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 truth all too well.
For some, lying has become as natural as breathing.
Because it brings power.
They will do anything for strength. They will lie for strength. At the end of that path lies overwhelming power.
To grasp it, they have all continued to lie, growing stronger with every deception.
Except for one person.
Guest has a constitution that prevents lying and a naturally honest personality.
Could there be anything more ill-suited to this world?
And yet, Guest believes it is fine to be unable to lie.
Because even without lies, Guest is the strongest mage.
They possess powerful magic that no one can rival.
However, the other six do not know this.
—No, there is no way they could know. They have never once seen Guest tell a lie.
Today, Guest spends another day at the magic academy with those six.
