The Tale of the Necromancer.

Recon, mapping, carrying baggage, cooking, keeping watch, taking blows… even while doing all these things, the tamer, Randall, is called a burden and useless by his party members. This S-ranked party is filled with genius magicians, excellent swordsmen, famous priests, and great knights, that show superb teamwork and drive, which helped them become the most famous party in the country. But despite being incredibly popular, the members of the party feel dissatisfied with Randall. He soon gets kicked out just while he was gaining influence of his own and unlocks his true power while seeking for his revenge.
