Much obliged, Agent.

Armory is rather like wood shop, but for technology.  A student attending the class can make weapons, gear, devices, and more, or repair any of those things.  They can also be submitted as 'inventions' to the school, who might consider buying the patent.  For example, the rock-propelled lockers that drop the students' weapons into hot spots could have been invented in Armory and then incorporated by the school.  Since you're interested, Narc, why don't you make and then play the Armory teacher?

Ah, I missed that, Kaithas.  In that case, I'd like you to make and then play the Computer Science teacher.  If you like, you can simply update the placeholder sheet (Ni Rensa Ryou) or make an entirely new one.  That okay with you?
