trying to remember anime/game

i remember seeing this clip on twitter of a mecha girl who was pink/white i think? and she was shy was really cute and i remember looking into it a bit more and it was from an anime that was based off a game

all i remember is that there were like two games for it and an OVA and i think one season of an anime for it? i also remember that the creator of the series was a big name like Kojima or something…

i know that’s very vague but if anyone can identify it just off that, i’d really appreciate it!
