Protective Lexy is found in the 9th Chapter of the Void Quest within the Midnight Channel. It always appears alongside either the Ardent Dancers or the Monomaniac Fuzz Shadows. The two skills - Tetrakarn and Makarakarn - give the Protective Lexy its name. It is highly recommended that the Protective Lexy be destroyed first because of its use of Tetrakarn and Makarakarn on other Shadows. Upon defeat, Protective Lexy may drop the Guard Cloth material. Selling 10 Guard Cloths at Daidara will unlock the Kid's Hachimaki accessory in the shop.
In Golden, it appears in Chapter 5, 8 and 9. It may drop Bloodstone for trade at Shiroku Pub.
Protective Lexy is a shadow appearing in the Evil Spirit Club. It must be defeated with Darkness-based skills for its conditional drop, Lexy Cotton, which is required for Theodore to produce the Segaki Rice and Curse Paper items, which cast Hamaon and Mudoon, respectively.
Protective Lexy appears in Acts 1 and 3 of Hikari. It does not attack, instead protecting its allies with Safeguard. When defeated, it may drop Lexy Gem and Lexy Button. Lexy Gem is used to create the Parrying Dagger for the P5 hero, the White Rose Whip for Ann, the Stiletto for Mitsuru, the Ote-gine for Ken, the Egoist Coat armor, and the Crusader Plate male armor. Lexy Button is used to create the Bloody Estoc for Mitsuru, and the Bus Stop Sign for Shinjiro.
