Aaah, finally, Kohaku & Nero picture. Professor look too humanlike, though...

Sacchin? Is that you in there?

Well I guess we know what happened to her in the Near Side routes...

......is that a long lost brother of alucard?

Nero is more... exotic.
It's funny, though. Nero/Satsuki make's a fine Al/Victoria team.
But Kohaku is far from Integra. Akiha is on the other hand. That also explains Ciel.
Give it a longer thought and maybe the whole Hellsing cast be there...

This pair is not as unlikely as you would think, if you considering how Kohaku -really- is.
