The second season of TV anime 'Dr.STONE' will begin its broadcast in January of 2021. Its opening song will be Fuji Fabric's "Rakuen," and ending song will be Hatena's "Koe?" 

'Dr.STONE' is an anime adaptation of Inagaki Riichiro and Boichi's manga that's currently being serialized in 'Gekkan Shonen Jump.' Kanazawa Daisuke (Key), who wrote and composed "Rakuen" explained, "It's a song that sings about people like Senku and Tsukasa, who disagree while seeking their own 'paradise' and continue to move forward as they face troubles." This song will be released in CD format on February 3, 2021. 

Meanwhile, Hatena, who wrote "Koe?" commented, "It's a song that was written in the image of Senku who is calm and cool, yet curious and passionate about saving the world."
