E-5 Stage Boss of the Operation AL/MI Summer 2014 event.

Basically [[Aircraft Carrier Oni]] with torn clothes and glowing red veins all over the monster-ship bits. It's easy to confuse the two.

As she sinks, she begins to talk normally instead of the usual reverberated voice of the abyssal bosses, a voice that is sometimes identified as [[Akagi (Kancolle)|]], given how the event is essentially a re-enactment of the [[Battle of Midway]] where she was critically damaged and scuttled. Both even share the same seiyuu: [[Fujita Saki]].
