Akira Kaiba

Akira is Hana's adoptive brother and one of the heads of the NKC.

Deck
Akira runs a "Titanium" Deck. His monsters focus on an aggressive strategy, with stats and effects powerful enough they need drawbacks, while the Spells and Traps Cards provide protection and handle their drawbacks.

After Hana goes missing, Akira mixes some of her cards on his deck. Since "Titanium" monsters include "Titan" in their names, they work with "Titan" support as well, allowing Akira to skillfully merge both decks while being granted protection by his daughter's cards.
