Well, Since Buddhism From India, and there is a lot of Indians can talk Arabic and if you return to Arab history you well see that the Arabians roles India. So this my guess.
Also if you return to Fakku.com and watch Byakuren Vs Yuuka go to page 11 and you will read what shou's say "Is just the thing for her to rehab"
W...Why me...!?That's right.Something like that, correct?Hijiri-san, you can understand that!?Wait, why did she even change languages!?WHAT!?"Your abilities are wanted, so help us out."I need your abilities.
Please help.
I wasn't that bad.
This is Arabic text, but which specific language? (Dari, Farsi, Pashto, etc.)
