This is perfect for bondinf between guardians! And Ben barely knows any of them! How would you feel if Ben offered his place for the night? (Also holy shit. Good post.)
Oooooo this is the fun part where we get to determine who does what in a combat situation. Who's the guy up front? Who's the one flanking? Who's suppressing while someone goes for the kill? You know, things animes should take into account.
None, at the moment. Most people never show interest past being a guardian. But Artemis (RainDash's subordinate) is more active than Benjamin (my guardian). Everyone is Vongola, the only difference is going to be the ring you get later.
