Yu-Gi-Oh! GX - Chapter 015

Separation...and Determination! is the fifteenth chapter of the Yu-Gi-Oh! GX manga. It was first printed in Japanese in the V Jump magazine and in English in the Shonen Jump magazine. Both of which were printed in volume 2 of the Yu-Gi-Oh! GX graphic novels afterwards.

Plot
The scene briefly shifts to the present practical skills class, where students are pitted against one another. Syrus Truesdale worries about the possibility of dueling an Obelisk Blue student, but Jaden Yuki is excited. Chazz Princeton doubts that Koyo Hibiki would give him Terra Firma.

Midori Hibiki notes Jaden is having fun. She then thinks about Winged Kuriboh having a spirit, and wonders if the few who know their cards have spirits would have to pay a price.

Back in the past, Jaden returns to see Koyo and sees that no visitors are allowed. Midori has him come in, and he sees that Koyo has been in a coma since just after the duel, and will be in it indefinitely. Jaden promises to become a duelist, and then he and Midori notice Winged Kuriboh's spirit. Jaden runs to the roof of the hospital, where they had dueled, unable to accept Koyo's condition. Winged Kuriboh's spirit follows him up there, and he recognizes what it is.

Back in the present, Jaden faces an Obelisk Blue student in the class, and beckons his "partner" to come with him. Midori concludes that she does not know what Winged Kuriboh is, but that Koyo is still alive because of him. Jaden, stepping up to his duel, thinks that he's keeping his promise to Koyo, training to become a duelist while wearing the same red that he once wore, and promises to have a fun duel with Koyo when the day comes.
