Gang of Yuusha: Potion Junkie to Percibell no Koubou  

Shouji, despite being born into poverty, possessed the traits of a hero known as a "yuusha." However, he spent his days being lazy, consuming alcohol and potions. He earned a living through violence. One day, he met a talented alchemist who owed debts. Her potions were exceptional as they were incredibly pure. Shouji no longer sought fame or honor; instead, he considered smuggling these potions into the criminal underworld. To do so, he brewed a potent item that got people high, sought out dirty money and companions for his gang, and clung onto the potions that gave him power. With these potions, he challenged the demons that lurked in this demi-world.
