Trivia[]

  • The far left side of the Limited Edition B cover features the outfit that Hamaura Ayano wore for their cover of "Nen ni wa Nen (Nen'iri Ver.)" on the OMAKE CHANNEL.
  • "Start Line" has the same title as a solo song written and performed by former Up Up Girls (Kakko Kari) member Sato Ayano.
  • It was released on the same day as Nakajima Takui's album, BEST YOURS II 2010-2020 Double Decade.
  • For a limited time, fans who purchased the single at select stores would get one of six clear ticket holders as a bonus.[10]
  • Towards the end of "Seishun no Hana", the members sing the same "la la la" part that was featured at the beginning of "Shalala! Yareru Hazu sa" while mimicking the choreography.
  • Starting February 29, all release events for the single were cancelled in consideration of a new policy established by the government to prevent the spread of COVID-19.[11]
    • As a result, this is their lowest selling single, lowest ranking single, and also their lowest first week sales.
  • This is their only major single to not have an Event V.
  • The embedded subtitles of the "Seishun no Hana" music video on YouTube has a typo at the 2:02 mark. Instead of "spit", it says "split".
