Thanks to Being Expelled From the Clan, I Was Released From the Hardship of [Buff]-ing Everyone in the Clan

Ninya only possessed one support skill, 【buff】.
As a result, she was unable to participate in the battles.
That was Ninya’s assessment within the clan.
Finally, the clan decided Ninya was useless and expelled her.
Ninya is abandoned in the dungeon by the clan members.
Everyone assumed Ninya, who couldn’t fight, would be eaten by the demons in the dungeon.
And when Ninya herself gave up on life in the face of the demons—
—○Skill 【buff】has attained level 99. Now that it has reached level 99, the skill will now evolve○—
A voice from Heaven could be heard.
And the clan that had exiled Ninya later collapsed.
Nobody had noticed.
Ninya was constantly applying a 【buff】to the entire clan.
Dark at first, but ultimately heartwarming.
