Well, given our great capability at producing airframes, that aircraft would ahve been used as spare parts long, long before it got to a condition where it had to "crab through the air" in order to fly a straight course and was so shot up it's skin's structural integrity (remember, in stressed skin aircraft the skin is a crucial part of the aircraft's strength) was that comprimzed.
Yes, it was Ki-100s. There is also an N1K2-J story. I think it was the one versus a squad of Hellcats in which 4 Hellcats were downed and the N1K2-J survived. Both the Ki-100 and N1K2-J stories are demonstratably falsified by US loss records.
