The new Opening Theme is デュエルしようぜ！ Duel Shiyou ze (“Let’s Duel!” by オーイシマサヨシ (Oishi Masayoshi)

His genres tend to be J-POP and Rock, as well as “AniSong” (Theme Songs explicitly written for Anime). Songs people might know him for are HOLLOW HUNGER from Overlord Season 4, UNION from SSSS.Gridman, uni-verse from Gridman Universe, and Role-Playing from Dragon Goes House Hunting. He also wrote and composed (but did not sing) the theme “Youkoso Japari Park he”, from the Kemono Friends series.

He comments he’s quite honored and excited to do a theme song for Yu-Gi-Oh! finally.

The new Ending theme is “STAR RUSH” by 七瀬彩夏 (Nanase Ayaka), an increasingly prolific voice actress, she has sung songs before but they’re essentially all character songs from Anime. Though Ms. Nanase has not been announced for a role in Go Rush!! nor is she an existing character.

One of her most recent roles is Ageha / Cure Butterfly from Soaring Sky Pretty Cure

She notes the song is meant to be stylish and refreshing for kids watching the show in the morning, and it’s meant to give a feeling of growth and reaching a brand new ‘universe’.
