Wait,something wrong with Koruri's birth date. If she is born in 1998, that mean that she is 25 but she is only in her 4th year of college meaning she should be younger. Alsoif you consider the photo on it was taken when she have done the passport then what Sakurako said is wrong, because that was in 2018 and Koruri would have been 20. Unless Koruri is a ronin, there is a problemin term of age.
