    • [2020] Hajimete wo Keikenchuu (初めてを経験中) (SKY PerfecTV! Twitter)



    • [2021.11.28-] BAKUNAI



    • In the March 2014 issue of Gekkan Entame, she was ranked as the 2nd member who "eats the most" in Hello Pro Kenshuusei.[31]
    • She wanted to join Hello Pro Kenshuusei because she thought she could get her skills up.
    • For her, the hardest thing about joining Hello Pro Kenshuusei was people telling her, "But you made it so far in the auditions..."
    • She thinks she won't lose to any other member in singing.
    • She wants to be an idol that is admired by everyone.
    • She is the second Hello! Project member from Actors School Hiroshima, the first being Sayashi Riho.
    • When asked why she wanted to join Morning Musume, she replied that when she would go to their  concerts, the members seemed to shine and she thought "Ah, I want to do that too!".
    • She says she wants to do solos. She wants to convey her energy to the people listening to her singing and for them to be moved.
    • When asked who she aspires to be like in Hello! Project, she said Sayashi Riho. She sees her as a "dai-senpai," and says that her dance isn't even comparable to Sayashi's. Upon joining Hello Pro Kenshuusei, she wants to work hard to get even a little bit more closer to her(in terms of aspiring to be like her).
    • Her Hello Pro Kenshuusei rivals were her generation-mates, especially Funaki Musubu. They were rivals in the Morning Musume audition, and they all joined Hello Pro Kenshuusei at the same time, so she doesn't want to lose to any of them.
    • Before her first Kenshuusei performance, she was nervous, because she had spent most of her time in lessons just watching herself and others, but now other people were going to be watching her. She was happy seeing the audience wave their glowsticks in time with their dance.
    • Her dream was to join Morning Musume after getting a lot of lessons and practice in Hello Pro Kenshuusei. If she can't join Morning Musume, she'd be happy to join a new unit.
    • Tsunku's comments: "You can't call yourself a pro if you don't have both the rhythm and a heart-felt song down. You can't just be good, you need to feel the more subtle rhythms and include emotions, so I want you to try copying more and more of the world's best singers to get to that point. Memorize everything about all the female singers you can."
    • According to an interview with JUNON in July 2014, Dambara hopes on getting a red member color.
    • She has the same birthday as Morning Musume 5th generation member Konno Asami, former Hello Pro Kenshuusei member Maeda Irori and Morning Musume 10th generation member Sato Masaki.
    • She went to karaoke many times with her mother to practice Hatsukoi Cider.
    • In an interview with Top Yell in July 2016, Dambara was nicknamed "The Future Legend".
    • Her future goal is to make people happy and give them energy.
    • Her family is always telling her to stop being so noisy, but she can't help wanting to sing.
    • When she hears her older sister singing, Ruru joins in and sings in harmonization.
    • She won't lose to other Kenshuusei in her love for music.
    • Her appeal was singing some of Matsuura Aya's Zutto Suki de Ii Desu ka.
    • She wants to challenge her shyness.
    • Haga Akane's debut was the most surprising to her. She was more mentally prepared for the debuts after that.
    • With many of the girls from her generation getting into groups before her, she had thought about quitting. She'd actually gone out and said that she wanted to quit three times. But when asked in return if she'd quit if that were the case, she'd reply 'It's not like I particularly want to quit!' and keep at it. She's competitive, and is the type who doesn't want to quit until she gets some sort of result.
    • When her group had yet to be made known, Morning Musume would have been her first choice. But she was happy to have gotten into Juice=Juice. It hadn't crossed her mind as a possibility because the group had never taken in new members before.
    • She's the last of her generation to debut in Hello! Project.
