Tenpei Sato is a Japanese composer best known for his work on the Disgaea series and other Nippon Ichi games set in chaotic underworld settings often called Makai, meaning demon world. His music mixes classical orchestration, jazz touches and exaggerated theatrical motifs to match demons, prinnies and over the top battles. Joker fits that style and circulates online under the Makai Universe name, shared by fans of anime style games who reuse short soundtrack cues for edits, memes and character introductions.
