Thief Knight Kiros (盗賊騎士キロス Tōzoku Kishi Kirosu) is the wild-card equestrian knight of the Underground, allied but not loyal in any way with the Underground Empire Tube.

Character History

Kiros had an infamy of being the great thief of the underground; the man who could steal anything and make his own, hiding his treasures in a cave beyond the reach of any forces. However, two years prior to the start of the story, Kiros encountered something greater than all of his treasures, seeing the bathing body of Princess Ial and immediately wanting her for his own, even if she wanted nothing to do with him. However before he could try and win her over, he became trapped within the underground's infamous "Whirling Hell", a vortex of winds said to be inescapable by anyone. For two years Kiros remained trapped until he used his abilities to develop a move known as the "Crescent Screw", which was powerful enough to raise him out of the Whirling Hell and back onto safe land. Yet in the time he had been trapped, the underground had changed, with Ial becoming frozen for her traitorous actions on the surface, including falling in love with the human male Takeru.Ep. 27: Thief Knight Kiros!

Discovering Ial's current fate and witnessing the troubles the Tube forces were having with Takeru and his Maskman comrades, Kiros approached Earth Emperor Zeba in gaining an alliance with him, under the condition that if he defeated the Maskman, the frozen Ial would immediately be given to him as payment. Though none of the other Tube forces wanted Kiros involved, in particular Igam, Zeba allowed Kiros to ally with them seeing his power as required for managing their enemies. Kiros immediately goes to the surface and easily manages the Maskman, using his Crescent Screw with a Doggler to destroy their Shot Bomber, but at the same time unleashing constant hatred at Takeru for being the man Ial fell in love with instead of him.Ep. 27: Thief Knight Kiros! Though his anger was mostly against Takeru, Kiros did attack the other Maskmen as he saw them as his enemies as well, including one attack on Kenta seeing him as the greatest threat in reaching TakeruEp. 37: Soldiers Who Bet on Their Dreams and striking against Akira after an incident where Blue Mask attacked him while he was doing research on other mattersEp. 35: The Mystery of Zeba! The Forbidden TombEp. 43: Akira Loses His Eyesight! The Mysterious Spell; he even at one point changed Haruka and Momoko into thieves to assist in gathering wealth for Ial's revival!Ep. 41: Female Thieves Haruka & Momoko

Though holding an alliance with Zeba for the Maskman's disposal for the sake of making Ial his own, Kiros never had any true allegiance or respect for the Earth Emperor. He knew there was something wrong with his existence and wanted to prove that Zeba was a fake and did not deserve the throne. Following a lead regarding a possibility that Zeba was in fact the infamous Lethal Doggler, Kiros opened the tomb the traitorous Doggler was in hoping to prove that he was associated with the creature and discovering that the tomb was previously open and only a Doggler guarding it remained. Kiros continued to try and find evidence of Lethal Doggler's connection to Zeba, he collected a stain of blood from the creature in another research trip, each one making the emperor panic by what he would discover. But all of these leads would ultimately turn out false after Igam ends up awakening the remains of Lethal Doggler in the pond he was born in, disappointing and yet confusing Kiros due to the strange connections he had seen otherwise yet not discovering the real truth behind the emperor.Ep. 35: The Mystery of Zeba! The Forbidden TombEp. 43: Akira Loses His Eyesight! The Mysterious SpellEp. 46: Counterattack! The Secret of the Demon Pond

As Tube started to fall apart from constant failure, Kiros found an opening to finally get Ial his way without assisting Zeba any further when Earth Imperial Commander Baraba was given one final chance to stop the Maskman. Taking advantage of the general's scenario, he forces Baraba to go into the frozen crypt and remove Ial's tomb from within. However when he saw Baraba was going to destroy the frozen princess instead of handing her over, he ends up secretly removing the bombs on her and taking her away on his own. Once he finally had Ial in his hands, Kiros left Baraba to be dealt with by the Maskman while taking the frozen girl with him back to the one place no one could get to him: the Whirling Hell.Ep. 48: Baraba! Death by Treachery

With Ial finally his, Kiros tried to figure a way to free her from the ice seal even as both Takeru and Igam continued to pursue him and get the princess back for their own purposes. Once back in his hidden treasure room, the thief enlisted the help of Earth Imperial Ninja Oyobu, who ended up becoming frozen in the prison previously but freed himself using his own life-shedding fire abilities. When Kiros tried to force Oyobu to use this fire on Ial, he ends up instead attacking him, hurting him and leading him to be struck in a relentless assault by the ninja, Igam, Fumin and even the Doggler that controlled the Whirling Hell. As he lays dying, Ial's frozen tomb is finally opened by the love and Aura of Takeru, making Kiros tragically witness in his death their loving embrace, seeing the one thing he could never steal as his final sight.Ep. 49: The Revived Princess Ial



Kiros's main weapons are a knife and a sickle which he carries into combat. Using a sickle and chain, he can manipulate his powerful "Crescent Screw" attack, which was powerful enough to escape from the Whirling Hell he had been trapped in.
