Bantu

ittle is known about Bantu's background outside his history with Tiki and his strong resistance to madness, unlike other Manaketes.

Prior to the events of Shadow Dragon and the Blade of Light and its remakes, Bantu took pity on the Divine Dragon Tiki, who was sent to sleep in the Ice Dragon Temple by her mother to protect her from lapsing into insanity. He then chose to, against Gotoh's strict instructions, rouse her from her slumber and thereafter explore the human realm with her. At some point of time during his travels with her, the two were separated. When Marth visits the Lefcandith village that he later takes up temporary residence in in Chapter 7, Bantu, in a state of panicked agitation, urges him to aid him in locating Tiki.
