Koga Sadame (運命虎雄 – Sadame Kōga) is Jugo's big brother.

Info
Debut: Chapter 1

Gender: Male

Age: 20

Infernity
Before leaving home, Koga used to play an Inferinty Deck.

Achromatic
Afterwards, Koga runs an Achromatic Deck, focused on using "Colorless" monsters that ignore other cards, as well as using Synchro Monsters to perform Xyz Summons.

Since Koga mixes Synchro and Xyz Monsters, his Deck theme aludes to the color "grey", the only achromatic color, which is also the result of a mixture of white and black.
