User blog comment:Sung5614062/When did Celine appear in th anime?/@comment-7948498-20150305044435

The first anime series didn't follow the manga's story very accurately. The OVA attempted to reconcile the anime with the manga, but still didn't explain Oshizu's body. Celine first appeared in OVA ep 5 as a giant flower, and then appeared in OVA ep 6 in her baby human body, neither of which with any explanation.

It wasn't until Motto To Love Ru that the anime was mostly back together with the manga story.
