The Ultramarine Orb Elixir (紺珠の薬 'kanju no kusuri') is a medicine created by Eirin Yagokoro to assist in solving the events in Legacy of Lunatic Kingdom. The elixir is apparently known to all Lunarians. This was hastily made by Eirin when she discovered a Lunarian invasion was underway in Gensokyo in the efforts of making up for the youkai being unable to comprehend the incident and the humans being too weak to stand against Lunarians despite her inability to interfere.
The main power of this Elixir is to remove the impurity of death and allow the user to experience the immediate future. Gameplay Mechanics wise this meant players could restart from the end of the previous "chapter" upon death, rather than at the beginning of each stage. Taken logically, it's basically a time loop.
