Got some more context. Using the cross on a grave yields this bit of text.
=> I'm an explorer!
オ-ッ キミモ タンケンカッ!
=> Oh, you are also an explorer!
ボクハ モウシンデシマッタカラ ダイジニシテイタ
(Context? Because the meaning looks weird. Who say that? The hero? A NPC?)
ピストルヲ キミニ アゲルヨ! ガンバレヨ
Here's a/the pistol! (I'll give you a/the pistol!) Good luck!
I know the first two lines are dependent on which class you choose. They should change as follows
=> I'm a clergyman/churchman!
オヤッ キミモ ダナッ!
=> Oh, you too? (means : "Oh, you're also a clergyman/churchman?")
=> I'm an Esper!
エッ? キミモ ダッテェ?
=> Eh? You too? <= (means: "Eh? You're also an Esper?")
(Remember it's engrish because I'm french, so you will have to check the sentences for spellings/grammar errors (but seeing the size of the sentence, I hope I didn't do any).
