Fly Me to the Moon manga volume 14 features story and art by Kenjiro Hata.

Nasa’s students are making a horror movie! But when things get a little too real, Tsukasa grabs a sword and gets busy slaying monsters. Cutting a swath of destruction is easy for our heroine - but showing her feelings for her husband? Not so much. Fortunately, the gang has plenty of ideas for ways she can show her affection, from saying those three little words to bonding over ice cream to wearing fancy underwear to bed. If only Tsukasa had the nerve to go through with any of it.
