ねえ、懐、入っていい?

A phrase said by [[Shinano Toushirou]] from [[Touken Ranbu]]. 

It translates as "Can I stay close to you?", but literally it means "Can I be in your bosom?".

Shinano has a fixation on being physically close to the Saniwa more so than other swords. This is because of how tantou swords were carried close to their owner's chest, and Shinano was regarded more as a treasure than a weapon. Of course, fans like to joke with the phrase, since the more literal translation of it sounds sexually suggestive.
