Nen × And × Nen.
Episode Description:
In Wing's room, Gon, Killua and Zushi are being taught by Wing. He explains the 4 main principles: Ten, Ren, Zetsu and Hatsu. He demonstrates how Ren works, by giving Killua the idea of killing him. Because of the strong pressure, Killua is forced to back off. Wing advises them to train with Zushi and start mastering Ten but Killua suggests that they should leave. Killua reveals to Gon that Wing was lying all along as his teachings don't explain Zushi's extreme resilience he noticed while fighting him. Zushi is troubled because Wing lied to them. Wing only says that for them to know the other meaning of Nen is dangerous...
