King of Fighters All Stars for mobile

Turns out that the game was released in Japan only as of this time and I have a feeling that it will be compatible with later IOS & Android devices as it uses 3D graphics. The character cast ranges from KOF 94 to KOF XIII. Some of the recognized tracks from previous KOF games are rearranged for this game and they are quite good. Needless to say, the gameplay is so much of the same as KOF 97 OL which I found it to be mediocre in my opinion so I'm not sure if KOF All Stars is a better game or not.
You do get to draw character cards and battle cards for gameplay use and there are tons of characters to choose from. The game has some of the new original characters who are unplayable. The one who's seen in most parts of the game is Noah. She may be nerdy in my opinion like she knows things about KOF tournament although there will be issues for proper decent communications between her and various KOF characters like you shouldn't dare to mess with them or they'll do something to you for getting in their way or some sort. I guess that she may be a manager, announcer, reporter or tournament host in this game but like KOF games, things are not going to end smoothly and the winners will have to deal with the evil opponents. Plus, the game has its own original boss characters to deal with.
One cool promotion, Athena, from the KOF series, had a role of Virtual YouTuber. A Virtual YouTuber is different than the standard YouTuber and it has been a hit since last year. Things to criticize about Virtual Youtubers:

1. Interactivity with invisible objects.
2. Not all VTubers have proper backgrounds.
3. Model clipping issues - A flaw that looks impossible to fix.
4. Certain kinds of contents are interesting while the others aren't. It may be true for other YouTubers' channels, virtual or not.
