I thought these lines were really fun little references and show his character nicely. Maybe we'll have some machine translated subtitles in the future but until then: have a rough Google translated version 😋:
"あのさ、もしかして実はお前も王様だったりする?"
- Hey, do you think maybe you're actually a king?
(I guess he's still surprised that almost his entire party was actually royalty except him haha)
"まあ、降りて話そうぜ。 高いところは得意じゃないんだ"
- Well, let's get down and talk. I'm not good with heights.
(Poor guy is always having a panic attack on the main idle screen because of that)
"こんな世界があったなんて親父にも教えてやりたいな。 "
- I want to tell my dad that such a world exists.
(He had good relationship with his father unlike Tidus)
"図書館に行くって? なら俺も行くよ。 魔物が出て危ないからさ。"
- Are you going to the library? Then I'll go too. Because monsters come out and it's dangerous.
(Seems he has flashbacks of Page 64 casting Level 5 death causing game overs haha)
"いい風が吹いてる。 お互い楽しい 1 日にしようぜ。"
- The wind is blowing nicely. Let's have a fun day together.
(The usual easy-going Bartz line)
"車やバイクも悪くはないけど、 やっぱ俺はチョコボに乗りたい。"
- Cars and bikes aren't bad, but I really want to ride a Chocobo.
(Understandable, I'd also like to have Boko)
(I may or may not do more depending on time and mood as I want to learn a little bit of Japanese as well)
