At the question of hus master, even under his mask it was obvious his face softens quite a bit. It was sort of a sensitive subject, but one he still talked about anyway. It just showed how much he cared, which might be why he understood why Gokudera was so desperately looking for his companion too.

"My previous master... he passed on a long time ago. He was an amazing man that I will always be proud that I served under him well... Oh but my new master is kind too! They care for me and a whole lot of other swords! They're back home though so they aren't here with us."

He paused for a moment, flustering for a moment as he flails his hands in front of his face.

"O-Oh but I'm not alone here though! My partner is here! And another companion too! So I'm not lonely!"

Not that Gokudera was assuming he was lonely, but he started blurting things out now.
