Omake: How Black Knight would been implemented in the gameplay chapter.

*Black Knight stares at Ike mid-battle as the latter kills a general and leads the selected units to escape.*

Zephiel: Um, that Knight over there has been staring at Ike for quite some time...

Hector: His blade is trembling... No wait, I think he's trembling. Yup, he's one of those "guys".

Lyn: What does that mean?

Hector: It means he REALLY wants Ike (to fight with him, he's like Karel)...

Lyn:... RUN IKE! FORGET THE BONUS EXP CLEARING CONDITION!
