Dragon Pet The two kanji here mean "nurture" and "dragon"

※This is just imagination. Meaning this item doesn't exist in real life.

Hmm, let me guess, you're expected to take care of and love this thing as if it's a real pet, right?

Here's a glass of water♡ One of the translators on my team translated this into "Here's some water". It didn't sound grammatically correct, so I decided to change it into that above instead. I'm still unsure if this is good enough though, so correct me if you find any errors!

...that sounds pointless.
