Ninja Legends and Shinobi Warfare in Chunin exam vs Kojima are different because Ninja Legends for chunin exam is aggressively difficult and impossible to win because of Kojima's deadly move (stun 3x and -20% HP burn 3x) while in shinobi warfare is very very easy and simple within just one mission that kojima is the only opponent to face (restriction instead of stun and fear (weaken) instead of burn) and will receive a chunin promotion.
