Asano Ruri and Yukimi-oneechan advice corner for Vtubers.
At one point Ruri-nee mentioned menhera and oneechan laughed really loud.
Patra playing a Gundam game, but it's something else.
Here's Hanabasami Kyo's cover of Ao no Sumika
Also a song that might make you feel old/nostalgic, Harusaruhi's cover of La La La Love Song
From Long Vacation, a 1996 TV Series.
From Flare's Watermelon Game stream where she launches fruits.
Suisei's stream earlier also has her launching a cherry while trying to speedrun.
As someone who also sat through the same story section of the vtuber you linked, I too also took a lot of screencaps and kinda ruin the tensions here and there. Some of the CGs are quite cool and wallpaper-worthy, to be fair.
And yes, the whole 'use your own student thing' is gonna be something that she might have to do again at later story bits.
The next one should be easier for her since it's a DPS check and she has spent quite some money to get her student waifu track Mari. Would be interesting though to find out her sensei character pulling out her adult (credit) card in front of a skinsuit and belt wearing nun.
She also needs to clear 2-2 and see glorious Toki and Rio in action.
EDIT: She accidentally cleared Hiero off stream so yeah time for Eden Treaty 4 and Mika's smile (I can fix her).
