The Second Magic (第二魔法, Dai Ni Mahō?), known as Zelretch or Kaleidoscope, is one of five remaining Magics.


Kischur Zelretch Schweinorg had already achieved it several centuries ago when he used it to kill Brunestud of the Crimson Moon. It is said however that even Archer, the only known Servant from the future, would be unable to comprehend it.


The little that is known about "Kaleidoscope" is that it encompasses the Operation of Parallel Worlds. Zelretch himself uses it frequently to move through parallel worlds, though due to his age he cannot use it as extensively as in his youth. Two of his inventions, the Kaleidostick and his trunk, also use the Second Magic to some degree. In hollow ataraxia, Rin Tohsaka attempted to create a "miniature of a miniature" of the Jewel Sword in the form of a pendant that would allow her to observe the 'waves' from parallel universes, but this failed spectacularly.

Multi-Dimensional Refraction PhenomenonEdit

The Multi-Dimensional Refraction Phenomenon (多重次元屈折現象, Tajuu Jigen Kussetsu Genshou?) is one fragment of the Second Magic, which is essentially the ability to create openings into parallel universes. One can then interact with the 'other side' through this gap.

The Jewel Sword and Tsubame Gaeshi, Assassin's sword technique, are both capable of causing this phenomenon.

Parallel worldsEdit

Parallel Worlds (並行世界, Heikou Sekai?, lit. "Adjacent Worlds") are the set of extant parallel universes.

Parallel Worlds are normally accessible to others only through the Second Magic; though, in Fate/Extella, Archimedes and Dark Eliza are able to Slide between them by way of a System Administrator privilege granted by SE.RA.PH. Characters of many different settings can interact and gather in Ahnenerbe.

Fate/stay night UniverseEdit

The three routes of Fate/stay night can be called parallel worlds existing at the same time in some sense. When asked how the routes would appear to Zelretch, Kinoko Nasu stated that Zelretch observing the routes as parallel would make it "true", and that Nasu would prefer that only one route existed instead.[4]

Fate/kaleid liner PRISMA☆ILLYA UniverseEdit

Fate/kaleid liner PRISMA☆ILLYA has portrayed two existing worlds, there is the "World of Illya" and the "World of Miyu".

Apocrypha UniverseEdit

The world of Fate/Apocrypha is a parallel world to Fate/stay night where the timeline differs during in the Third Holy Grail War.

Moon Cell Holy Grail War UniverseEdit


World lines of the Fate/Extra series

The world of the Moon Cell Holy Grail War shares the same events at that of Fate/stay night up until a certain point until a "certain major incident" in the 1970s that caused the world's mana to start drying up causes it to split off into its own separate universe. As of the 2030s, the world's mana was completely gone.[5]

Tsuki no Sango UniverseEdit

The world of Tsuki no Sango takes place in approximately the year 3000, when humankind arrived at the peak of its civilization, but is losing its will to keep living.

  • It is a world in which the events of Tsukihime didn't take place.[6]
  • Unlike the world of "EXTRA", Tsuki no Sango is a degenerated world where magecraft yet lingers.[6]


  1. Staff Roundtable - The Second Night
    Speaking of Tohno, did you ever think of doing a crossover with 「Kara no Kyoukai」?
    Nasu: No, even though the word rules (special powers/magic) are the same. They're both just small happenings in a single world. That's why the first main character I made is Aoko-san.
  2. The Bamboo Broom Diary, August 14th - "Clock Tower 2015 is in the world of Tsukihime and Mahou Tsukai no Yoru. In that world, a certain someone XX in order to protect the present, and so the events of FGO don't happen. No one knew about his achievements but he protected both the past and the future.
