My dearest Montblanc, I think of you always. If we could meet, I would much like to tell you how I feel in person. —Mogumi, Townsgirl
Reaker only appears in "Mission #089: Moogle Bride", where she set up the trick in form of a townsgirl and wanted to give Montblanc a "lesson in humanity". Because she is the leader of Clan Rose, Reaker became the enemy boss. At the ending, she said that she and Montblanc would be perfect together.
Reaker's Japanese name, "Reika", means "lovely flower". This is related to her clan name, while her alias "Mogumi" is a formation of "Megumi", which means "blessing". Otherwise, the name "Mogumi" might be based on the Final Fantasy IX moogle, Mogmi. Another possibility could be it is a play on the Japanese pronunciation of "moogle", which is "Moguri".
