Yukio Goto

Yukio (由紀夫) is a character ???. He poses as the mysterious thief "Kaito Shounen" (怪盗 少年, lit. "Phantom Thief Boy").

Appearance
Currently seen only in his thief outfit, Yukio wears what appears to be a gray tunic over a black shirt with two red bands over both arms. He wears black pants and a pair of blue, black, and grey boots with a yellow zig-zag pattern at the top. He keeps his hands covered with blue gloves and wears a grey cape along with a similarly colored top hat (though not pictured above). He has messy, crimson and cyan colored hair, though he changes the style depending on his current disguise/persona.

Personality
Beyond having a flair for the dramatics, not much is known about Yukio.

Biography
Yukio, as "Kaito Shounen", is seen sneaking around a high-class party looking for a supposed "top-secret file". Upon finding its location, he is confronted by three guards.

Deck
True to his alias, Yukio uses a "Phantom HERO" Deck, based around Gentleman Thief-like "HERO" monsters. The Deck seems to have no true strategy outside of swarming and dealing direct damage (both through direct attacks and effect damage). He is apparently able to match any Summon his opponent uses, hinting that the Deck is multi-Summon based (outside of the Fusion Summoning he demonstrates).
