Shachibato! President, It's Time for Battle! - S01

Long ago, a goddess came down from the heavens and blessed the barren land of Gatepia. In her wake, enormous gates appeared, leading to dungeons filled with "kirakuri"-crystals that hold the world's essential energy. Over time, adventurers formed companies to harvest these crystals from the dungeons. After his father vanishes inside one of Gatepia's largest gates, Minato is convinced by his childhood friend Yutoria to take over as president of his father's treasure-hunting company, the Kibou Company. Hesitant but with little choice, he steps into the role and meets the rest of the team: Makoto, a priest; Akari, a soldier; and Guide, the accountant. Now leading the company, Minato and his companions take on missions and odd jobs to keep their struggling business afloat. Along the way, they begin piecing together the truth behind their former leader's mysterious disappearance.
