Accelerator is hax.

The downside of playing from a canon that originated as a light novel series is the lack of translated canon for the later stuff. The anime only covers light novels v1-6. The manga covers approximately the same, though it's currently on the Accelerator and Last Order arc, which was volume 5 in the light novels. There are 19 light novels out now.

Accelerator has canon in volumes 8, 12, 13, and 15. Possibly later ones, but I'm not entirely sure.

Anyhoo! I was discussing with a friend about whether Last Order remembers the events of episodes 19-20. When Accelerator did a diff on her data and reverted her to her state a week earlier, she obviously lost her memories of him from the last two days. But~

( Cut for spoilers. )

I was already aware of #1, and #2 makes perfect sense. This brings to mind the circumstances of #1, though. A little more chance searching revealed these amusing threads on boards. I'm especially amused by the Accelerator vs DBZ Goku fight discussion.

So apparently if I were to canon update Accelerator he'd get a pimp cane and angel wings. ( What. )
