I'll be assuming again that this fairy is PO2C Mukai Takamasa, one of I-8's crew, was left a float and lost conscious until he was rescued by a small boat from USS Morrison DD-560, the destroyer that sank I-8, Mukai was interrogated by the Americans.

Mukai testified that I-8's gun crew engaged Morrison from 900 yards in an exchange of gunfire, Mukai rushes to her twin 14cm 40cal. Type-11 naval gun, Mikai was hit by several debris on his chest and legs when Morrison pounded I-8's bridge. Mukai relentlessly keeps on firing I-8's guns until Morison's 5-inch guns shattered the submarine until she capsized, all 128 crew including her captain, CO. Shinohara Shigeo, went down with I-8 except for Mukai.
