先週に引き続きセイバー物です。
今回は「お尻を眺める」シリーズで私服バージョンのセイバーです。

The following is English explanation.
Title : [MMD R18] We tried to look at the bottom of Saber.
It is the Saber one after last week.
This time, it is Saber of a mufti version in a " it looks at a bottom " series.

Still more, this English is a decodement by the translation software, we think that there is the part which the interpretation is difficult by probably but please pardon.
