"Ossan wa Nimotsu demo Mottetero yo" to Shinjin ni Namerareteru kedo, Jitsu wa Saikyou no Kengou desu

**Liebert** is a middle-aged swordsman going nowhere fast. Ten years ago, he was the sole survivor of the hero party that defeated the Demon King after a desperate battle, and was once considered the kingdom's greatest swordsman. However, traumatized by his failure to protect his comrades, he lost the ability to wield his true power.

Living a modest life, even looked down upon by novice adventurers, he was one day visited by **Aria**, a girl he had once tutored in swordsmanship.
She had been chosen as the new Heroine and came to recruit him for her party.
Burdened by his trauma, Liebert initially refused the offer. Unbeknownst to them, surviving commanders of the Demon King's army were launching an attack on the city, aiming to eliminate Aria.
Witnessing Aria standing alone against the threat as the Heroine, Liebert took up his sword once more. He resolved to join the fight and challenge the resurrected Demon King as the swordsman of the hero party.
However, the other party members, **Aisha** and **Iska**, were not pleased with Liebert's inclusion...
Will Liebert be able to earn their trust?
A new adventure begins for the **"veteran swordsman"**, finally freed from the chains of his past.
