Future Card Buddyfight EP23 - Drum's Heroic Adventure!

Drum returns to Dragon World to seek advice on becoming stronger from his father. He asks Drum if strength is all Drum wants and then kicks him into Dungeon World, where Drum gets equipped with a new weapon and armor. He saves a village by inadvertently slaying a rampaging golem monster. The villagers (who look similar to Gao's human friends from Earth) then believe that Drum is a legendary hero and request him to defeat the king of the monsters in the mountains. After being given a stone tablet that is reminiscent of a Buddyfight deck, Drum uses it to summon other heroes who closely resemble Tasuku, Baku, Kuguru, and Tetsuya to aid in his quest. Although the group was initially disorganized, Drum eventually realizes that working together and not giving up are keys to getting stronger. He finishes the quest and reports back to his father, who then kicks Drum into another world for more training.
