You guys... are freaking out right now... No, you guys shouldn't do this. Here's the thing: There's Shirona in the screenshot, but where's Meloetta? She ain't there ain't she? You guys are judging ONE screenshot out of how many for an opening and concluding, "Yup, Hikari's going to be here for only a few episodes." I got another official page that told that 'revival' of Hikari and Pochama including Shirona. Revival means to bring back to life or to start again. That should mean something, maybe Hikari will be around the whole season but not always with the group. You guys got to think out of box for this, you all are too stubborn. I say, let's wait until we see results, because no one said anything more than returning people and a new character. If Shirona's on the promo for season 2 AND in the FIRST screenshot so far, doesn't conclude what you guys are fearing of. Thaaaank You.
I'm not giving up on you. You don't understand this yet, but people need you.
