nugimashou ka?

A phrase that the Touken Ranbu Sengo Muramasa says in the Citadel (どうかしましたか? 脱ぎまショウか?/Dokashimashita ka? Nugimashou ka?), roughly translating to "What's the matter? Shall I undress?"

Muramasa makes several references to stripping down in his quotes, with little rhyme or reason to do so. Many jokes are had with this quirk, having Muramasa strip for the flimsiest of reasons much to the ire of Tonbokiri.
