In the campaign mode, at the opening and transition part, the character subtitles (characters and subtitles next to them as shown below) and voice will fast-forward, i.e., the subtitles will flash by, while the voice will play overlappingly (the audio is played at constant speed, but some of it will only play one sentence and then be overlapped by another voice, and only the last voice is fully finished), so much so that it is completely impossible to experience the full story background.
