http://www.mangago.zone/read-manga/shiny_star/uu/v01/c007.1/pg-1/ actually he meets Hikaru in this crossover extra but you may want to read Hikaru's story first not to get spoiled or smth ..Shiny star is his story
Thank you!!
I will make sure to read it (≧∀≦)
I kinda was expecting more tbh... Like them meeting with the actual hariku or hariku shows up and use the fact that yamashita like him so much to his benefit... I feel like the actual story was finished in ch 2 or sth and the rest are just extra
