DESCRIPTION
Honoka is a good kid. She is a great athlete but suffers in the academic department.
Kariu is academically gifted but feels like she can't compete with her fellow classmates. She also tries very hard to be great at volleyball but falls slightly short of Honoka.
Comparison is the thief of joy and that is what Kariu suffers with.
...but Honoka pushing herself so hard where she faints caused a huge RIFT between both girls in this episode...
