After hearing Longinus Gill story and all the determination and zeal in Longinus Gill voice, Jigoro Kuwajima decided that Longinus Gill has a potential to become a slayer, so Jigoro Kuwajima offered Longinus Gill to became his/her sensei, and of course, Longinus Gill agreed. (Your sensei - your breathing style)

Training was tough, but Longinus Gill determination and zeal helped him/her to endure everything that Jigoro Kuwajima made Longinus Gill went through. At the end of the training Longinus Gill became much stronger and ready for the Final Selection...
