Slight correction, but during Suisei's first solo live, it was their first time singing The Last Frontier together. They already sang together before.Basically : "Suisei's first time singing with AZKi was during Suisei's first solo live. She was told that AZKi was getting near the end of her career, and thus, Suisei thought that it might be the first and last time she would ever get to perform with her on stage."
Some LiveTL from AZKi's ongoing stream about 5th FES
[EN] For the new pioneers... When I was writing The Last Frontier, 2021, Whoa, it's been 2 years already...
[EN] I met sui-chan at INNK music, but then after a while Suichan Transferred to Hololive, and I stayed back on INNK music focusing on Music, as a Vtuber-Vsinger-
[EN] We kinda started walking different paths back then, she had her goals and her dreams. So did I too.
[EN] Trying to figure out how to use music to live as a Vsinger-Vtuber-, so the routes separated
[EN] I had a bit of a regret... I wanted to make an Original song with Sui-chan... It was kinda sad that we never managed to.
[EN] for those that know, INNK and Azki's project was kinda ending at that point. That's why I was kinda figuring out what to do heading towards that end point.
[EN] That's why not being able to make an original song and sing with her was a bit of a regret
[EN] So I used that momentum to just go ahead and do it then
[EN] I thought it was best to do it now that I had come up with the idea
[EN] I worked super hard, wondering if Sui-chan would sing it all the time. But f I didn't do it now, we would never be able to afterall
[EN] You probably have that one friend that you were super close to back in middle school, but after going to HS you go off on each other's ways, but because you are separated it becomes harder to
[EN] keep in contact
[EN] I can say it now, because it's been 5 years now...
[EN] There was such a time... yeah
[EN] That's why it was kinda hard to contact her...
[EN] We were both doing our own things, and she definitely had her own hardships back then

[EN] We sang "The last frontier" and then the MC came up
[EN] then we started talking about the Lyrics...
[EN] I tried to ask her when was the last time we sang this song... And then she starts taking something out...
[EN] She started doing something that wasn't in the script, but the staff knew
[EN] I didn't expect to receive a letter from Suichan during the MC
[EN] I have the letter right here...
[EN] SHE GOT ME, I really couldn't stop her at that point
[EN] I was listening carefully while crying a lot
[EN] I can't remember what I said after that apart from shouting Capture the Moment!
[EN] I asked her about the time she sang Inochi on one of her lives. Where she cried during the song.
[EN] like "What were those tears about"
[EN] I was a mess, but Sui-chan was also crying okay?
[EN] right as soon as we got back to the backstage I just went "Sui-chan you idiot~~"
[EN] Fubu-chan and mikochi were waiting back there
[EN] Mikochi started crying too all of a sudden
[EN] As son as everything was over, we all became a mess
[EN] Because I didn't stop, I can be together with everyone... So I told everyone that

A really sweet part
[EN] but because we never stopped, is why today exists... I realized
[EN] It's not just me that did it, but because I have you all Pioneers
[EN] Without you now wouldn't be possible
[EN] Now I'm surrounded by all my friends, and got the message that it was great I didn't stop
[EN] thank you hololive, It's so warm here
[EN] I am not alone anymore, and am with my friends now.
[EN] so much happened in these past 2 days...
[EN] Sui-chan's smiling.. but she was crying too you know
[EN] There's a lot of pioneers that have been cheering me from back during INNK, and also those that support me nowadays... It feels like a miracle
[EN] Right after the live ended, I got a LINE from Gozaru-san that said: "I Cried"
Suisei denies crying, it was just raining in the venue.
