A show about WWII-era warships personified as cute girls does not sound like a likely source of DID scenes, yet Arpeggio of Blue Steel does have a few:
episode #11, 11:30 - a cute-girl "mental model" is thoroughly wrapped with chains as a metaphor that her weapons have been locked down
episode #12, 16:30 - another cute-girl "mental model" has split into physical and digital forms and both end up as a DID, the former restrained by some sort of energy bands and the latter by the cyberspace equivalent of wires
