Why this ? (Teto) look so mad

the mad one is burnout Teto btw.

No? That's synthesizer Teto

is it?

lemme check

they look real similar

ok so burnout Teto is wearing the synthesizer fit.

that is indeed burnout.

No??? This is not a forsaken meme

shes actually from a creepypasta.

Ok, I don't know if it's from forsaken or not so thanks for telling that ig

she (Teto i think)feels lost and betrayed, possibly mirroring Miku's fading spotlight as others (like Neru/Muse) gained popularity, leading her to become a Forsaken character seeking her own voice.
