So I have a Japanese Senran Kagura 2 cart and I installed the DLC from CIAngel one day and it went good everything came up in the game. I got all DLC costumes and quests. But the DLC disappeared from the game after I was trying Luma3DS region emulation thing. I saw someone did a emulation where it changed the game region and language so I tried to change it to USA EN but nothing happened except the DLCs gone. I changed everything back to the way they were but still no luck. I also tried to reinstall the DLC many times but still can't get it to work again.
