I put it in a sleeve immediately after taking it out. I'm selling it because I pulled it myself in an event map and it duplicated with the ones I purchased. It's harder to get than Akizuki-oneechan, so I recommend it to those who can't seem to encounter her through drops. Equipping three Akizuki cannons and a Type 13 air radar Kai (improved) in the extra slot will make her a great asset.
