Oh, that's a while...I got Haku and Sen all the way back at the end of March, I think? [When he started to run out his Bond time and decided he'd just get some familiars and bullshit to people that he had a Bond. Which, to be fair, did end up a bit necessary since it took him almost 4 months to get a Bond rather than the 3 after which he would've seriously risked exploding.]

So they've grown a lot in that time, though they were only barely puppies when I got them, honestly.
