Every once in awhile DW releases an event of significantly higher difficulty that you unlock by clearing a more difficult singularity than the standard fuyuki.

They do this to please players who like to face challenges(im one of them lol). The standard events can be fun too but without challenge quests like these the game feels too easy and becomes boring. The added difficulty spices things up occasionally.
