Placing this OVA chronologically is a bit tricky. As best as i can determine, the bulk of the story takes place during the events of, but prior to the final scene of, Episode 11: "Sealed Reliquary". The ending portion of the OVA takes place some time later and seems to be just after the events of Episode 13: "Diffraction Mother Goose". In terms of viewing order, the least confusing placement is probably after ep11, however (due to the dialog and written messages in the final scenes), the spoiler free option would be after ep13. I personally prefer the latter, but use your own discretion.
