Takeru Teshimine

(天子峰猛 Teshimine Takeru; Seiyu: Shinichiro Miki) - Little of him is known about either his history or powers, save that in a flashback he's seen brandishing two weapons that look somewhat like tonfas. But judging from the trend of GetBackers names reflecting the characters' abilities or attributes, it is interesting to note that Teshimine literally translates as "Emperor of the Peak". It can be safely assumed that he was the one who found Ginji shortly after he was abandoned in Infinity Fortress. He raised Ginji as a young boy before he disappeared (in flashback scenes where he was shown with Ginji, Ginji's hair was still black). He first became prominent in the Infinity Fortress arc (where MakubeX was making an atomic bomb). Teshimine dropped by the Honky Tonk, and left Paul a disc. The contents of the disc was later revealed in the Voodoo Child arc as a program to stop Ginji from draining Infinity Fortress dry when he rampages as Raitei. It's assumed that he was the ruler of Infinity Fortress before the era of VOLTS. Like the first-gen GB, Teshimine, too, has the 'Stigma'. He has also revealed to Ginji that his (Ginji's) mother is in Babylon City. (Popularity rating: 16th with 125 votes)
