The Summoner Who Commands a Beast Army - Episode 2

After a roadside fight, a troll is killed in one hit by two Slimes. The captain and officers scan them with Bole Glasses and discover the Slimes are Tier-5 with an S-rank skill, Indestructible Body, and — impossibly for Slimes — unlimited growth. The team realizes slimes normally cap at Tier-3, so these beasts and their number could upend Sternhold if the news spreads. Tension rises as more infinite Slimes appear. Then a stranger approaches, murmuring, "I don't have much to offer, please forgive me." The group ends the episode asking, 'Just who is this man?'
