Go to the Dolworm Crystal Palace (ドルワーム水晶宮) [Gatara Capital → Gatara Fields → Chaldea Mtn. Road → Gobble Desert East → Dolworm Kingdom / Crystal Palace] and head up to the Sky Garden (空中庭園)[you can use Divine Machine(神カラクリ) to 4th floor] on the 5th floor and give Menme's Memo to Tuda (トゥダ) at C5.
Go down to the 2nd floor and in the Laboratory (研究室), check the bookshelf on the far left (from when you enter the room) to obtain the item Gataraian Technology Compendium(ガテリア式技術大系).
Return to Menme and give her that item. Wait 3 real world minutes before talking to her again.
