The Time Warp Rifle is a weapon made from Lunar technology. It is a weapon found within the hyperverse. The gun itself is 3 dimensional, but it has the ability to manipulate the 5th dimension, allowing the bullet to somewhat time travel...
Upon pulling trigger, the target aimed at is instantly hit. This is due to the 5 dimensional manipulation. This means that it is impossible to dodge the bullet after the trigger is pulled. "You cannot dodge a bullet that has already hit".
The gun itself looks very futuristic, being black and grey with cyan highlights. It is a very large rifle, with a long single barrel and a large scope on the top.
The Time Warp Rifle was originally from the psychological horror "Koishi Komeiji's Heart-Throbbing Adventure", being the weapon Reisen II uses.
