Artifact: New Heaven & Earth Wave Cannon

A Spell Card of Tenshi Hinanawi from the world delirious with eternal summer (a Touhou LW original). She fires a water cannon with the power to pierce through Heaven and Earth from her Universe Ring. If history had followed its proper course, this Spell Card would have probably been called ''Keystone: Qian & Kun Rumbling Cannon.'' Apparently, when used by its original owner, the Universe Ring takes the form of a bracelet or gauntlet. But when thrown, it expands in size, destroying everything in its path. When the ring was lent to Tenshi, it decided that remaining in its enlarged state was most fitting. However, this seems to have annoyed Tenshi, who can't see directly ahead when driving it.
