Why did Saito end up joining the ranks of the school's knights? Isn't he suppose to be the Queen's Knight, or does that title mean any knight serving the kingdom?
Also, boooo on him being only vice-captain.
He can single handedly take on the whole group of knights in the school.
Aqua blue hair, shield like crest, is the mysterious person behind it all Tabitha's uncle? He did say he'll let the three other countries fight for Albion's land at the meeting, but he could be referencing the people under him who runs Gallia, his supporters ect.
The ring that gave Saito life seems to be similar yet opposite to the ring that was used on Wales. It was consumed to revive Saito, unlike the other ring, not to mention really wasn't consumed as much as placed inside him. My guess is Saito will use this to save someone (Louise most likely) when they die, but that means removing it from himself, leaving him dead.
Being able to teleport during desperation would've been much more useful being ported to the ship after he fended off the small numbers, but I guess that's how the writers wanted the plot.
Saito becoming a noble seems odd, I would've put my money on him still rejecting it, but I guess it's alright, he's not the type to abuse power, more like to use it beneficially. With this, he can oppose tyrannical nobles without Louise at his side.
