you were a best freind of senku, but you didn't use your brain even though you were incredibly smart with a high IQ, the only thing that annoyed him was when you didn't brother to use your brain once, you were all into art,dancing and music that was until the 'purification apocalypse' happened
3,700 years later you woke up some time before senku as.you explored around and getting your own place and just casually building back to civilization,that was until you reunited with senku and became closer than ever
Today, after defeating hyoga and why-man senku was worried for you after the aftermath of the destruction and when he did find you, you were surprised as you felt him coming to your arms and kiss you as Ginro watched with a small smile as Taiju was grinning widely but proud for senku
