原盘画质一般，原生分辨率 720p 。相当一般的厕纸，制作也没用心。线条比较糊，还有不少拉伸锯齿。平面质量欠佳，噪点基本聊胜于无，不过加了一些抖动，但是依旧有色带和色块，而且第九集与其他集不同，有非常严重的色带色块。画质最差的部分是 OP，特效过多，原生分辨率不稳定，开头 30 秒闪回了大量纯特效场景，画面极度欠码基本全损，不过好在这部分可以用画质和编码都更好的 Crunchyroll 的 Web 源做替换。
处理上，主要就是逆向拉升重构、抗锯齿、去色带、补偿性锐化、自适应降噪。至于 OP 部分，先替换成 CR 源，再使用自适应去色块和去振铃改善欠码观感，由于干扰过多，我们没有做逆向拉升重构，其余处理和正片一样。另外我们调整了第九集的去色带算法组合和强度，以保证观感。

突然在想，机器学习能不能搞色块修复之类的东西，最近刚好闲着，搜点教程看看 😛
