/jp/ - Otaku Culture

Chink Honkers updated to 2.9. Main content is the rest of chapter 9 (not available until March), Chinese New Year stuff, a new S rank Rita and an awakened form of Assault Mei. Grind for some new materials, spend them to upgrade her core level, reach level 3 (out of 6) to get her new costume. It's all permanently available so no rush.

Not sure what the special stages are for the CNY event, but you'll be able to get a free Fuka costume. Himeko and Mei have new costumes, but those are both paid. You can also get a Houkai core fragment, 3 equipment tickets, 2 special gacha tickets and some gems during the event.
There's also a cute little public room to hang around in and do pic related.
