Rowen Hasiba, known in Japan as Tōma Hashiba (羽柴当麻 Hashiba Tōma), is a member of the Ronin Warriors and is considered by some to be the most intelligent of the group, which causes the Dark Warlord Dais to describe Rowen as the most cunning and therefore the most dangerous of the Ronins.
He supposedly has an IQ of 250 and often serves as the voice of reason in the group as a counter-balance to the hotter tempers of Ryo and Kento. In the TV series, he is portrayed as having a thick Brooklyn accent, but that accent went missing in the OVAs. His father, Genichirou, is a "mad scientist" and is often too busy to see his son. His mother (name unknown) is a journalist who travels a lot and doesn't see much of her ex-husband or her son, treating them both as friends, rather than family. She first appears in the YST CD drama Tenkuden (The Legend of Tenku). Rowen is close friends with Sage, as they share similar interests.
Rowen wears the Strata armor, called Tenku (Heavens) in YST. His virtue is Inochi (Life) in Ronin Warriors, changed from Chi (Wisdom) in the original YST. The armor's principal weapon is a collapsible bow which is attached to the back of the armor, along with a small metallic quiver, from which a seemingly unlimited amount of arrows can be drawn. His surekill is Arrow Shockwave, called Shinku Ha (Vacuum Wave) in YST. The attack consists of firing an arrow that energizes to instill devastating explosive capacities upon impact with the target, releasing a powerfully destructive pillar of light. (The first use of his surekill demolished a large section of a mountain). He is voiced by Ward Perry in the English dub.
Like the other Ronins, Rowen gained a new suit of armor in the 3rd OVA, Message; however, its powers and abilities remain unknown.
Rowen's name Hashiba is most likely from Hideyoshi Toyotomi's original last name, Hashiba. Toyotomi was Oda Nobunaga's successor, and unified Japan under his rule for a short while.
