"Act 30 Infinity 4 Haruka & Michiru - Sailor Uranus & Sailor Neptune -" is the 30th chapter of the Pretty Soldier Sailor Moon manga series and the 4th chapter of the Infinity arc. It was written and illustrated by Naoko Takeuchi.


Sailor Uranus and Sailor Neptune reveal themselves to the Sailor Guardians. Chibiusa and Mamoru sculpt the Holy Grail, and Ami battles Yui Bidou, who is Viluy of the Witches 5.


Chibiusa recalls that Neptune called her to mirror a Talisman, which the rest of the group were told to find in their vision. Neptune and Uranus tell the rest of the Sailor Guardians that they have no intention of fighting with them. The duo attacks them and makes their escape. Later, Luna tells them that Neptune and Uranus are Sailor Guardians who, like Pluto, were never to be known to the rest of them and that they were charged with protecting them from a distance. Chibiusa begins her school project where she has to make something out of clay. She hopes to make something called a Holy Grail, an object that Neo-Queen Serenity used in the past that made her more powerful. Ami plans to go to Mugen Cram School to investigate the place further. There she meets Yui Bidou, the only student who scored better grades than Ami. Yui shows Ami a miniature replica of a nebula she made, called the Tau Nebula.

Kaolinite sees Ami in her fountain, sensing a powerful force from her, concluding that Ami must be a Sailor Guardian. Yui who is another member of the Witches 5, Viluy, is sent after Ami. Michiru and Haruka see Ami run to the school laboratory and find a room filled with caged daimons. Students under the control of Viluy attack Ami, Haruka, and Michiru and says how she is using her nanobots to obtain Hoste. Ami breaks free and turns into Sailor Mercury. Haruka and Michiru also break free and all three flee the building. Viluy goes after Mercury and uses her nanobots to attack Mercury when the other Sailor Senshi shows up. Haruka transforms into Sailor Uranus and Michiru transforms into Sailor Neptune. Uranus summons her Talisman, the Space Sword and kills Viluy with it, saving Mercury. Meanwhile, at KO University, Motoki meets Reika's new acquaintance, Setsuna Meiou.
