70 years ago, the Bombing of Kure occured, with Ise, Hyuuga and Haruna (amongst others, including Tone, Aoba, Ooyodo, Ryuhou and Katsuragi) present, resulting in Ise and Haruna being sunk, and Hyuuga running aground due to damage.
Yeah, I just realized that after going over the strip again when I was more awake - swapped the 10 and 7 around.
It's certainly more peaceful now than before... even if Haruna is being squished by another battleship.
All a bit surprised that Hyuuga is like one of the few shipgirls who remembers everything... but we haven't seen too much beyond her, Akagi, and Yamato with regards to this, though. The latter sure remembers being thrown away.
