Drug intoxicated person 薬物中毒者！！

It is usually healthy quiet child.
However, it is a mutiple personality disorder person due to the nervous imbalance.

If the medicine is not taken, it becomes a brutal back character.

It enters the state to have gotten drunk on the medicine when the medicine was drunk too much oppositely and it becomes obscene.

How about such a setting?

Excuse me in strange English.

普段は健全で臆病な薬物中毒者♪
でも　精神不安定な多重人格障害者
精神安定剤（麻薬も可）が切れると裏人格に・・・

逆に薬を飲みすぎると　エロく卑猥になります☆
って　設定はどうかな♪
