Yobou Banka

Yabou Banka (誉望 万化) also known by his moniker the Boy with goggles (ゴーグルの少年) is a minor character that is introduced in Toaru Majutsu no Index. An operative of SCHOOL, he is the first member of the organization in their debut to be seen and the first one to be killed in action.

Appearance
He is depicted as having somewhat spiky hair. In Toaru Majutsu no Index, he wears a puffy vest over his shirt, while in Toaru Kagaku no Railgun he wears a flannel shirt over his shirt. His most distinctive feature is the metallic goggle on his face that surrounds his entire head just like Saturn's rings. Plugs are inserted into it all around, and countless cables connect them to a machine on his back.

Personality
Little is shown about him, but he didn't show any hesitation when dispatching an associate, Management, who had become too much a liability to SCHOOL's plans to be kept alive. He seems to be at least easy-going enough to laugh at the fact that the Man on the Phone mocked Kakine Teitoku for using wings.

Battle Royale Arc
Receiving word that Management has been captured by GROUP's clean-up team, he is sent to kill him, most likely to silence him in his association with SCHOOL's plot. He attacks the paddy wagon carrying Management, being rammed into a guardrail and then rips it in half. However, he leaves all the GROUP subordinates alive as he does this. After Management got out, still reeling from the wound he sustained against Tsuchimikado Motoharu, he finds the Yabou approaching him. Despite the pain, Managment manages a meek smile, apologizing for his blunder. Yabou says that he should not mind it for he is the one who should apologize. Management then asks how to unlock his handcuffs so that they can leave already. However, he suddenly screams as Yabou kills crush Management's hands and head, killing him, and says "too bad" to his plight regarding the handcuffs.

Yabou was apparently with Kakine Teitoku and the Girl in the dress while they wait for the security in the Elementary Particle Engineering Laboratory to be disrupted after Sunazara Chimitsu's attempted assassination on Oyafune Monaka. He, Teitoku, and Girl in the dress enter the facility to retrieve the Tweezers, and are later forced to engage against ITEM in battle in order for them to escape. He is later killed by Mugino Shizuri who then takes his blood-spattered goggles.

At the height of the Indian Poker card fad, the Girl in the dress have him look up on the Indian Poker cards as there are scientists leaving essences of themselves within the cards as insurance, and that information on the Tweezers have been leaked in one the cards. Using his computer expertise, he narrows down a list of conversations regarding Indian Poker, and wants the organization to investigate each one of them. One of these conversations comes from Saten Ruiko, a friend of Frenda Seivelun of SCHOOL. He orders a team to abduct Ruiko but are foiled by Frenda.

Meanwhile, he himself investigates one of the leads, infiltrating a facility on his own. Using his ability is able to copy the contents of an Indian Poker card from the facility and into the empty Indian Poker card he is holding. He is later contacted by the team he had ordered to get Ruiko, and found that they have been defeated by someone. Seeing that that there might be something bigger about Ruiko than he realized, Yabou orders Yumiya Rakko, SCHOOL's sniper, to hunt them down.

Abilities
Mugino Shizuri proclaims that Yabou was someone with any real power, though it is unsuited for combat, Yabou has an esper powers that is useful within the context of his organization's operations. It is revealed that he is "an esper that can skim fragrance components". It is demonstrated when he copies the contents of an Indian Poker card from an insufficiently airtight safe onto a blank card in his hand.

Other abilities
Yabou also uses technology for many purposes, from narrowing down a list of results in a search to be more relevant, to being able to infiltrate an entire laboratory on his own undetected.
