I'm reading Baka Tsuki's translations of the first novel now, and I'm struck by Haruyuki's love for (and skill at) First Person Shooters. And also remembering the collection he had back at home.
Considering all that, it's a bit funny that Silver Crow is purely a close-range combatant, without a single ranged attack.
Even Laser Sword is an Attack Enhancement technique, rather than a Range Extention, right? Rather than range, it increases the striking speed and damage of his <<Punch>> attack, while imparting a "cutting/piercing" quality.
Maybe he'll eventually get himself a handgun? Or would that be too "unheroic" for our protagonist, to shoot from the safety of the sky?
