Hatsukoi Time Capsule ~Osananajimi to Kya Kya Ufufu~

When he was small, Kiriya buried a time capsule under a Camphor tree with his 5 osananajimis. Soon after, one of his osananajimis Kazuha moved away and they lost touch with each other. Ten years later, his other four osananajimis Yuuna, Mio, Maika and Anna all attend the same school and stay at the same dormitory as him, but hold back their feelings for him. One day, Kazuha returns and asked him if he still remembers the time capsule and their promise. With Kazuha’s return, the other osananajimis don’t hold back anymore and start making their moves, resulting in chaos. Which osananajimi will he end up with?
