i like to headcanon that kusanagi is an actual historian
a.) i’m pretty sure he learned a lot of his disciplinary and general interpersonal strategies from classroom and academic situations, and just added some violence in for spice
b.) he got access to some pretty damn rare german documents during missing kings. you cant just do that. dude definitely has academic contacts.
c.) he doesnt seem like the type to go for a “happy go lucky” kind of career plan – he probably got at least one degree before becoming a fulltime bartender and focusing on homra
d.) on that subject – yknow what a favorite part time job for broke college students is? bartending. pays well, and doesnt usually conflict w class hours.
there might be stuff in canon ive forgotten that contradicts this but sshhhh i want to imagine kusanagi furthering his education
