A new collaboration might be coming

According to the official Nyan-ko X account, the Rurouni Kenshin collaboration is returning on October 9th for the Japanese server. It hasn't been decided for the Korean server yet, but there's a possibility. I only have Kenshin... Speaking of which, it's said that Kenshin's third form will be released in version 15.7. Kenshin is a character I used a lot in the early game, so I have a soft spot for him and definitely want to get his third form. If it returns to the Korean server, it will be the second collaboration, and they say new Uber Rare and Legend Rare units will appear, which sounds fun.
