Which Stars of Destiny give you the most anxiety because you've missed them in the past?

Which Stars of Destiny give you the most anxiety because you've missed them in the past?

For me:

Suikoden I - Leon and Sonya. Just Leon. Freaking Leon.

Suikoden II - Mukumuku. How many times have I forgotten you are a star of destiny? I don't miss anyone else, but I've forgotten about him more times than I can count.

Suikoden III + IV - I don't think there are any.

Suikoden V - Faylen and Faylon and Genoh. Missed Faylen and Faylon on my first playthrough, and then on a later playthrough forgot to talk to Fuwalafuwalu at the right time.
