Sen of Satuday was an armor that was part of The Original Seven. It was specially designed to fight in a combined form with Sin of Friday. It was owned by Melissa, who's twin brother Carossa owned Sin of Friday. This made them a formidable pair on the battle field.
When docked in The Original Seven satellite ring, Sen of Saturday resembled a chakram.
Sen is a member of the Original Seven Armors. It's designation was Saturday.
Melissa would summon and control Sen using a morphable chakram.
Sen is Sin's sister armor, but smaller. In its battle state it is more humanoid than its sibling but the head is very alien looking. In its compact form it resembles a chakram, which is also its weapon when in battle form.
The chakram is a deadly ring which can be thrown against an enemy and pierce its armor and will return to its owner like a boomerang. Sen can interlock with Sin to a single armor, where Sen resides in the interior and bottom section, protected by the stronger and bigger Sin.
Like Sin, it can fire energy beams and is protected by an electromagnetic shield.
Sen is one of three Original Seven Armors with a unique armor color, possessing the same pale gold as Saudade of Sunday.
Melissa used Sen's lasers and chakram to fight from a ranged distance. She would often hold back and allow Sin to fight up close with his melee weapons, while Sen would shoot from afar.
