The Labyrinth Raids of the Ultimate Tank (Saikyou Tank no Meikyuu Kouryaku)
Oh look, a light novel with a ridiculously long name, what a surprise!
Full name: The Labyrinth Raids of the Ultimate Tank ~The Tank Possessing a Rare 9,999 Endurance Skill was Expelled from the Hero Party
Romaji: Saikyou Tank no Meikyuu Kouryaku ~Tairyoku 9999 no Rare Skill-mochi Tank, Yuusha Party wo Tsuihou Sareru
Rude is a tank, known as the strongest in history. However, the Hero decided that his skills were worthless because he couldn't do anything but take damage, and threw him out of the party. His cleric friend who trusted him followed him to the remote village that Rude was forced to return to.
The story so far gave an impression that it has heart in the right place. Grown up protagonist doing his best for his frail little sister. A homunculus who is more human than it should have been. A comically useless hero? I like it so far and would like to read more :)
I was reading the manga when it was getting translated, many web novels and manga were starting to get translated during that time with the theme of the MC getting kicked out of the hero’s party. There were a lot of titles that are being translated and already were or aren’t, there was the defect healer, a necromancer girl, a warrior called a false hero, a mage with a guide book, a guy with a repair skill, a girl with an inverse skill, a guy who runs a herb store and is the older brother of the hero, a middle-aged man who had his adventurer license revoked while traveling with his daughter, etc.
