Last but not least, three laws of Do-Teihen Medical School, currently called Gachi'Ura by its graduates.
最後にド底辺医大の三法則を掲げましょう。

1: It is not the bottom medical school but its enrollee that is despicable, which deserves to be called a bona fide moron beyond redemption.
ド底辺シリツ医大が悪いのではない、本人の頭が悪いんだ。

2: The graduates of Do-Teihen are so ashamed that none of them dare to mention their own alma mater which they have gone through.
ド底辺シリツ医大卒は恥ずかしくて、学校名を皆さま言いません。

3: The Do-Teihen graduates are so ashamed of having bought their way into the exclusively bottom-leveled medical school
that they tend to call a genuine doctor a charlatan who elucidates their imbecility.
ド底辺特殊シリツ医大卒は裏口入学の負い目から裏口馬鹿を暴く人間を偽医者扱いしたがる。
