Those of you who are familiar with Ojousama wa Gokigen Naname will probably wonder, "Why did he just introduce a non-heroine character before anyone else?"  The reason is fairly simple... this is a game that is defined at least as much by its antagonist as its protagonist and heroines.  This one of about a dozen VNs I'm replaying in parallel (as the mood takes me), and it is one of my favorites... as well as one of the two reasons I keep playing Ensemble games, even though they've made nothing but shit for the past three years.

I'll let her introduce herself first, with a translated excerpt from her intro scene.

鶴美「はしたないなんて、そんな意地悪言わないで？ 私は仕方ないの」

Tsurumi "Don't be mean by calling me 'vulgar'. I'm hopeless.

鶴美「だってね」

Tsurumi "After all..."

たっぷりともったいつけ、今度は最高の笑顔を浮かべて、言った。

She took a long pause, giving me her best smile, and spoke.

鶴美「私はお金が大好きです♪」

Tsurumi "I love money!"

鶴美「子供の時も文集に、将来の夢『お金になりたい』って 書いたくらい、お金が大好きよ」

Tsurumi "I love money so much that I wrote that 'I want to become money' in an essay as a child."

鶴美「だから、仕方がないの」

Tsurumi "So, there is nothing that can be done about me.

元「……」

Hajime "..."

鶴美「世の中の人は、人生はお金じゃないなんて 平気で嘘をつくけど、私は素直で純真なだけなんだ と思うわ」

Tsurumi "People always lie with a straight face by saying that life isn't about money, but I think I'm just frank and pure.

鶴美「私はお金を手に入れるためならなんだってするし、 １秒でも早く、１円でもたくさん欲しい」

Tsurumi "I'll do anything to get more money, and I want as much money as possible as fast as possible.

鶴美「お金より愛が大事だなんていう人は、 貯金を全部私にくれてもいいと思うの、ねえ」

Tsurumi "I think that people say love is more important than money should give me their savings, don't you?"

鶴美「私、誰かのお財布から根こそぎ洗いざらい、 何もかも奪い取るのって、だぁ～い好き♪」

Tsurumi "I love nothing more than stealing everything from the insides of another person's wallet!

鶴美「それでも“愛”は残してあげるんだから、 それも許されるって思わない？」

Tsurumi "But I leave them 'love', so don't you think I can be forgiven?"

日本どころか、世界の長者番付の常連になるような人間が、何を言うのか。

It was hard to believe that I was hearing this from a person whose name was on not only Japan's richest people but those of the world as awhole.

『富める者は、庶民に奉仕する』

"'Those with wealth must do service to the masses.'"

本物の金持ちは、金に執着しないもの。だが、この人は生まれついての金の亡者だ。

True aristocrats aren't excessively attached to money.  However, this person is a born money-grubber.

この人が誰かに『愛してる』と囁く時。

When this person says that she 'loves' someone...

――それは根こそぎ奪ってやるぞ、という合図である。

... it is another word for 'I am going to steal everything  you own'.

何より恐ろしいのは、愛してるというのが決して嘘ではないという点だ。

More frightening than anything is the fact that she isn't lying when she says she loves someone.

この女はお金をくれるというだけで――たとえ、実際には奪い取っただけだったとしても、

This woman, if someone gives her money or even if she steals it...

その人物を心の底から愛することが出来る。怪物なのだ。

She is a monster capable of loving them from the bottom of her heart...

おかげで隠し子がいるといういかがわしい噂まで立つほどだが、それだけは絶対にありえないと断言してもいい。

Because of that, dubious rumors abound about her having an illegitimate child, but I can say that is impossible without a doubt.

鶴美は、異性でも、子供でもなく、お金そのものを愛しているからだ。

Tsurumi does not love the opposite sex, nor a child, but rather money itself.

鶴美「だから元くん？ 早くお金ちょーだい♪」

Tsurumi "So, Hajime-kun? Hurry up and give me some money."

As you can probably guess from the excerpt above, Tsurumi is... more than a little insane.  She doesn't hide her motives at all from Hajime (though he misunderstands them at times), and she is unbelievably ruthless in the pursuit of money.   She isn't a heroine... nor is she a potential heroine (with good reason).  She's the antagonist who defines everything that can go wrong with an individual as a result of exposure to the twisted nature of old, wealthy families.
