Event Japanese English Note
Play Introduction こんにちは。軽巡洋艦大井です。どうぞよろしくお願い致しますね Hello. I'm Light Cruiser Ooi. Pleased to make your acquaintance.
Play Kai 重雷装艦、大井です。ところで北上さんはどこかしら? I'm torpedo cruiser Ooi. By the way, I wonder where Kitakami-san is.
Play Library 球磨型軽巡洋艦の4番艦、大井よ。
I'm Ooi, fourth ship in the Kuma-class light cruisers.
I was born in Kobe.
I'm an active practice ship at the Navy School, you know?
Of course, I'll change into a torpedo cruiser if I need to fight for real. Nice to meet you!
Play Kai 重雷装艦バージョンの大井です。
It's Ooi, torpedo cruiser edition.
My torpedo powers were counted in, but I didn't have much of the limelight.
I'll show you what I'm made of this time. Keep your eyes open!
重雷装巡洋艦 = torpedo cruiser. '重' also means also 'enormous,' 'extreme,' etc. Not 'heavy' in this context. 重雷装艦 = torpedo ship.
Play Secretary 1 演習ですか? Is this some sort of drill?
Play Secretary 2 北上さん? あ、提督、なんですか? Kitakami-san? Ah, Admiral, what is the matter?
Play Secretary 3 提督…この手はなんですか…? 何かの演習ですか? …撃ってもいいですか? Admiral.. what's with that hand? Is this some sort of drill? May I shoot it?
Play Kai 提督も気になります?そう、足にいっぱい付いたんですよ!・・・って触りすぎなので、提督に20発撃っていいですか? You like them too, Admiral? Yes, I have a lot attached to my legs! ...but you've touched them too much, so how about eating 20 of them?
Play Idle 北上さん、大丈夫かなぁ……。私がいないと心配だなぁ……ん……心配……きっと、そう、きっと何か起きてる!私、行かなきゃ! Will Kitakami-san be alright?..... I'm getting worried as I'm not with her... Hmm... I'm so worried... It's definitely, yes, there's definitely something that's about to happen! I have to go now!
Play Secretary Married 提督?他の娘がどうしたって?…え?違う?ふぅ~ん…ならいいの、なら...。 Admiral? What happened to the other girls, you say? Eh...? That's not it? Hmm, it's okay then.. It's okay... It's somewhat a sign she's a Yan
Play Wedding 北上さん!・・・なんだ提督なの?あ、いえいいんですけど・・・はい、提督も愛してます! Kitakami-san!... oh ,it's the Admiral? Ah, no, it's fine.. yes, I love the Admiral too! (as in, loves the Admiral as well as KTKM)
Play Kai たった二人の重雷装艦、私を選んでいいの?…私を裏切ったら海に沈めるけどね… Of the two Torpedo cruisers, you chose me, right?... If you betray me, I'll sink you in the ocean, you know... Rather hypocritical, since she already has an interest towards KTKM (There's actually three CLTs now).
Play Looking At Scores 提督にお知らせが来ています There is a new message for you, Admiral.
Play Kai 提督に、お知らせみたいです It seems there is a message for you, Admiral.
Play Kai Ni 情報を確認するのですね、提督。 Checking on the report, Admiral.

Play Equipment 3 まあ、いいかな Well, I guess this works.
Play Kai 北上さんがいいって言うなら If Kitakami is fine with it, go ahead.
Play Kai Ni まあまあ、かな? This should be OK.
 ⇧ shared with expedition selection, resource collection, instant repair and development
Play Supply そう、燃料と酸素魚雷を満載してね……ふふ……。これでまた、戦えます! Yep, be sure to pack me with fuel and torpedoes okay? Fufu, this way I can fight again.
Play Docking Minor はい、少し休んできますね。 Yes, I'll be taking a short break.
Play Docking Major ちっ、なんて指揮…あっ、いえ、なんでもありませーん。うふふっ。 Tsk, what terrible command- no, it's nothing~. Ufufu. She has a habit of insulting the commander

Play Kai Ni さぁ、冷たくて素敵な酸素魚雷、本当の力を叩きつけてやるのよ! Now, I will strike with the true power of these wonderfully cold oxygen torpedoes!
Play Battle Start 私、砲雷撃戦て聞くと、燃えちゃいます I get all worked up when I hear about exchanging shells!
Play Kai さぁ、いっくわよぉ Ok, here I go!
Play Attack そうね、もう遅いわよ Yeah, you're too slow.

Anime oi


  • She is infatuated with Kitakami, as expressed in her quotes and in her behavior in derivative media as well as in the anime adaptation.
    • In the English dub of the anime, Ooi is much ruder when compared to her original counterpart, such as calling things insects when angered.


  • After being remodeled into torpedo cruisers, Ooi, Kitakami & Kiso can utilize the Kouhyouteki to attack during the opening torpedo phase.
  • She is named after the "Ōi river" in Shizuoka prefecture, Japan.
    • It literally means Big Well.
    • Isuzu class destroyer escort JDS Ooi had been commissioned to Maritime Self Defense Force (1961-1992), inheriting the name.
  • Torpedoed by USS Flasher 570nmi (1,060 km; 660 mi) south of Hong Kong in the South China Sea at 13°12′N 114°52′E, 19 July 1944.
  • Along with Kitakami, they were the first ships in the entire game to receive their second remodel on 13/06/2013.
  • Ooi loses and gains luck as she progresses to her Kai Ni form, her base starting with 17 luck, dropping down to 10 and ending with 13 on her Kai Ni.

ID1 OoiEdit



Not the Library ID, but the ID that indicates "your XXXth ship". Before the game was even launched, the game announced an automatic delivery of Ooi if you have logged in before the launch. This indicates that you are one of the oldest players, this understandably, is very rare.
