Sensou Suru Nara Yumi, Yari, Ken da Tatakae!
[If you're going to war, fight with bows, spears, and swords!]

This song starts playing as Alucard appears beside Seras in Order 07, having just stopped one of Alex's bayonets from impaling her.  It's quite cool.

[Japanese]
Sensou surunara yumi, yari, ken da tatakae!

Sono bashoga yoku mauze wakuwakuno ningen LAND
Hora CHECK hitonofuri tadasu wagafuri
Shimozewana RHYTHM mo nannosono kanenotame

Onakawa bugiwagi jabujabu yokuyokude dorodoro
Otsumuni habikori sekaikan BABY sonna antalachini horebore

Kamenga yoku nianze muchakuchauo kaibtusu LAND
Masani yomosue yatsuga SYMBOL
Kusatta bunkani takaritsuku haegatobu ujigawaku MANDELA ni beokamasu

Otakuwa muchimuchi jabujabu honnoude gushagusha
Otsumude katamaru uchukau BABY sonna antatachini omisore

Sorewo yattara ikemasen  Sorewo yallara mou sukiwanai

[English]
That place is very fitting in the exciting human land
Hey check out others' act then correct my own
I can care less for lowly assignments, all for the sake of money, living, vanity, and honor
My stomach is soaked and churning with greed
World perception spread in the head, baby I got a crush on you all

Looking good with a disguised mask in the monster's land
It must be the end of the world since HE is the symbol
Flocked with flies, infested with maggots, and farts at Mandela in the rotten culture

You are crazy mixed up with primal instinct
Universal concept shapes in the head, baby I'm impressed by you all

Don't do that.  If you do, there is no more savior.
