Tougen Anki 2nd Trailer The new trailer also features the anime's opening theme song "Overnight" performed by the four-member Japanese alternative rock band The Oral Cigarettes . The band's vocalist and guitarist Takuya Yamanaka said, "I'm very honored to be performing the opening theme for Tougen Anki! In this song, I tried to capture the spirit of the protagonist, who continues to uphold justice even when he’s far from his ideal self. I believe his circumstances are something many people can relate to in everyday life. Rather than living in regret thinking, “I wish I could’ve been more like this…,” my hope is that this song will give someone the push they need.
