for those who still havent read the trivia about the real warship, took it from kancolle wiki :
For many, Akebono is an odd ship. She's very verbally abusive, & unlike Michishio or Kasumi who have gentler sides, she never really seems to be appreciative. However, her history may have been a basis for this.
To begin with, Akebono doesn't really stand out favorably in history. Unlike her sister Ushio, Akebono is taken as the 'ship of misfortune,' while Ushio is the 'ship of fortune.'
1. Battle of the Coral Seas
Akebono was assigned to escort Zuikaku while Ushio was assigned to Shoukaku. In the middle of the mission, Ushio requested to switch with Akebono & Akebono agreed. However, American bombers heavily damaged Shoukaku yet Zuikaku got away without a single scratch. As a result, Ushio & Zuikaku were considered the lucky ships from this point on while Akebono & Shoukaku received the opposite. Similarly, rather than reprimanding Ushio, Akebono was reprimanded for Shoukaku's injuries. Akebono was then reassigned from the front lines to the rear.
This is reflected in Secretary(3) If you don't like me, why don't you just reassign me?.
2. January 1944 Escort Akebono & her sister Sazanami were escorting a fleet of supply ships. Enroute, Sazanami was attacked by USS Albacore (SS-218) & sank on the spot. Akebono launched 59 depth charges & drove it away; however, the delayed rendezvous with the supply fleet left it with no protection. As such, it was virtually annihilated.
This is reflected in her Library Intro, ....But, I'm a bit uneasy around subs...., as she not only lost her sister to them, but failed as an escort.
3. Battle of Leyte Gulf Akebono was once again assigned with Ushio. When Mogami crashed into Nachi, Akebono went to escort Mogami; however, the American air wings did not let up & further damaged the half-sunken Mogami. In the end, Akebono was ordered to torpedo Mogami.
4. Manila Air Raids The Americans were determined to finish off Nachi. At that time, Akebono was ported with Nachi & was the only ship able to immediately defend. Unfortunately, while facing innumerable aircraft, Nachi sustained several heavy hits & sank.
Naturally, Akebono was heavily damaged as well & Ushio towed her into the dock for repairs. However a week later, the American launched another air strike. Akebono's cannons, engines, & torpedoes were all but destroyed. She sank while being observed by Ushio nearby.
Closing notes If Akebono & Ushio hadn't switched back then, her fate may have been different. However Akebono doesn't blame Ushio for all of this - she is more angry at her superiors, who blamed her inappropriately & overlooked the circumstances at the time. That's why she insists on 'Kuso Teitoku' - she has a profound distrust of superiors.
