Ship DescriptionVIIA型潜艇—U-31VIIA型潜水艦-U-31Type VIIA submarine – U-31.
Biography铁血的VIIA型潜艇,U-31向你报到~不管是战斗还是保护指挥官的安全,都不在话下哦~啊,不过最近就先作为指挥官的贴身安保人员行动一段时间吧?保证不会让形迹可疑的孩子接近指挥官哦~鉄血のVIIA型潜水艦、U-31だよ。戦闘も指揮官の警護もばっちりよ~。あ、当分は指揮官の専属ボディーガードをやらせてね?怪しい子が指揮官に近づかないようにきっちり守ってあげる~Name's U-31. I'm an Iron Blood VIIA-type submarine. Fighting and ensuring your safety are my middle names! Let me be your personal bodyguard for now. I'll keep any shifty girls at arm's length from you!
Acquisition啊哈~你就是指挥官吗?U-31好像从第一眼看见你,就变得有些焦躁难耐了呢♪嗯~以后就让我们两个好·好·相·处吧~あは♡指揮官っていうのはあなたなのね?見た瞬間からなんだかソワソワしちゃった♪これからな・か・よ・くしましょうね~Ahah! You must be that "Commander," right? I felt all fidgety inside the moment I saw you. You and I are gonna be SUCH close friends♡
Login指挥官你来啦~先站着不要动哦,让我贴贴、闻闻、再摸摸~嗯,好像没什么被粘上什么窃听设备呢。お、来たのね~。はい、そのままじーっとして~。香りチェック!のちお触りっと…うん、盗聴器とかはつけられていないみたいHey, you're here! Hold still for a sec. I'm gonna give you a smell check, then a patdown... Alright, looks like nobody's wiretapped you.
Details嗯~安全检查时间到啦~就算是指挥官,为了以防万一也要仔细检查,快乖乖站着不要动~让我摸个够哦!はーい、セキュリティチェックの時間だよ~。もしもの時があるからしっかりチェックしないとね。ほらほら、動かないで。好きなだけ指揮官を触らせてねー!It's time for your security check! You can never be too sure when it comes to these things. Hold still, now. I'm gonna give you a full-body search!
Main唔~总是有些形迹可疑的孩子想试图接近指挥官呐,不过放心吧,U-31会一直紧紧盯着指挥官,不会有丝毫松懈的~うん、どうも指揮官に近づこうとする怪しい子がいるみたいね。でも大丈夫。指揮官から目を離さずにしっかり見張ってあげるから~Yup, there're shifty girls trying to approach you alright. But that's no biggie. I'll keep my eyes on you and make sure nobody pulls anything on you!
Main 2指挥官不许动!老老实实站着哦!让我闻闻闻闻~……嗯?!有指挥官之外的味道,是谁!?哦——原来是我的味道啊~指揮官止まって!そこでじっとして!くんくん……うん?誰かの匂いがするね…誰だ~?あは♡わたしの匂いじゃんHold it, Commander! Stay right there! *sniff sniff*... Hmm. You've got a smell on you – but whose? Ahah! It's just mine!
Main 3最近一到白天就变得没什么精神,但是一到晚上就变得很兴奋呢~看来很适合夜班执勤呢……指挥官,晚上我会在你床边保护你哦♪~最近、昼はやる気が出てないのに、夜になるとテンションが上がってるね~。気分はもう夜勤ってカンジ……指揮官、夜はベッドのすぐそばで守ってあげるよ♪For a while now, I've been feeling lazy during the day but then full of energy come nighttime. I should pick up the night shift... and keep you safe from right by your bedside♪
Touch指挥官是在提醒我对你进行今天的安全检查么~?指揮官、今日のセキュリティチェックをしてってこと?Is this a sign, asking for your daily security check?
Touch (Special)指挥官该不会在想“帮忙长大”之类很失礼的事吧~?指揮官ってまさか、「大きいほうがいいなあ」とか、失礼なこと考えてないよね~?You best not be thinking anything rude like, "I wish they were bigger"!
Touch (Headpat)欸~摸摸头就满足了?不会吧?えぇ~、頭をぽんぽんするだけでもう満足ぅ?そんなわけないでしょ?Heeey, you can't be content with JUST a headpat. You wanna go further, don'tcha?
Mission哎呀,指挥官,还有任务没有完成呢~当然,我会和你一起去处理的哦♪あら指揮官、まだ終わってない任務があるよ~。もちろん、一緒にこなしてあげる♪Oh, Commander, you've got unfinished missions. Before you ask – of course I'll help!
Mission Complete任务完成啦,是想要奖励,还是我呢~任務完了よ。ご褒美がほしいの?それともわたしのほうがいいわけ?Mission complete. Want a reward? Or would you rather have me?
Mail经过我的检查,这些信件里面没发现危险物品!嗯哼,不过有一些奇怪的粉色信件,但我已经把它们都没收了哦♪チェック完了よ。手紙の中に危険物ナシ!でも、妙なピンク色の手紙が何通かあったから、全部没収しちゃった♪Check complete. Your letter is perfectly safe! Buuut, I had to confiscate a few ones that came in suspicious pink envelopes♪
Return to Port辛苦咯指挥官~你坐在这里休息一下,我去把门锁上♪~嗯?为什么要上锁?当然是为了保障你的安全啦~お疲れ指揮官~。ドアをロックしてくるから、そこに座って休んでてね♪うん?なんでロックするかって?そりゃもちろん指揮官の安全を守るためだよ?Welcome back. You sit over there and I'll go lock the door! Hm? Why lock the door? It's to keep you safe, duh!
Commission Complete哦……!委托组回来了啊,我和指挥官一起去迎接吧!这样就能保证你一直在我的视线范围内了呢~あ。委託組が戻ってきたー。じゃあ指揮官、一緒に出迎えに行こう!そうすれば視界の中に指揮官を収められるもんね~Oh, the commission team is back. Let's head out and meet them together! That way you can do your thing, and I can keep you in my sight.
Enhancement又变强了啊~这离不开指挥官努力指导的功劳呢~また強くなったわー。これも指揮官が頑張って指導してくれたおかげだねI've gotten even stronger! And I couldn't have done it without your guidance.
Flagship哼哼~我可是不会手下留情的!ふふ~ん、容赦なんかしないわよ!Heheh! You're getting no mercy from me!
VictoryU-31这么强也是没办法呢~こんなに強いのも、仕方ないことよ~Woe is me for being so dang strong!
Defeat欸、欸欸?!是用了违禁的武器吧?あ、あれ?!ルール違反の武装を使ってたでしょ?!H-hey! Didn't they use weapons that're against the rules?!
Skill咕嘟嘟地沉入海底吧!ゴボゴボ海の底に沈んでけー♪Sink to the bottom of the sea!
Low HP这,这样可有点不妙啦……こ、これはちょっとマズいかも……Oookay, this is getting dodgy...
Affinity (Upset)……U-31还是休息一段时间再做指挥官的贴身安保人员比较好呢~……指揮官の専属ボディーガードはちょっと休みたいかなぁ~I feel like taking a leave from being your personal bodyguard.
Affinity (Stranger)指挥官喜欢什么发型呢?双马尾?或者是长直发?嗯嗯~果然还是最喜欢U-31这样的侧马尾了对吧?指揮官はどんな髪型が好き?ツインテ?それともストレートロング?それとも、やっぱりわたしみたいなサイドテールが一番好きかしら?What kind of hair do you like? Twin ponytails? Straight and long? Or maybe side ponytails like mine are your favorite?
Affinity (Friendly)指挥官问这个是什么?这个东西能监听指挥官办公室和房间里的所有声音哦,对于保护指挥官的安全非常有必要呢!これが何かって?これはね、指揮官の執務室と部屋のすべての音を捉えられるもので、指揮官の安全を確保するには必要なのよ♪You don't know what this is? It's able to capture any and all sound in your quarters and your office. It's essential to ensuring your safety!
Affinity (Like)嗯~我昨天好像录到了指挥官说的奇怪梦话哦~想知道是什么吗?抱抱U-31才可以告诉你哦♪~うーん、なんだか昨日指揮官の変な寝言が録れちゃって~。知りたい?ぎゅってしてくれたら教えてあげる♪Y'know, I picked up you saying some weird things in your sleep. Wanna know what? Give me a nice hug and I'll tell you♪
Affinity (Love)嗯~虽然U-31有很多优点,但果然还是长大点会更好吧?我保持现在这个状态就可以了?啊哈~原来如此,我正好在指挥官的好球范围内啊~指挥官很有眼光哦♪~うーん、わたしは今でもいいところはたくさんあるけど、やっぱもうちょっぴり大人になったほうがいいかしら?このままでもいいって?あは♡なるほどぉ、わたしって指揮官のストライクゾーンに入ってるってことね~。さすが指揮官、お目が高い♪I've got plenty of strengths as it stands, but maaaybe I could stand to be a little more mature. You don't think so? Ahah! I see, I see. I'm in your strike zone, is what you're saying. I knew you had an eye for quality, Commander♪
Pledge这一刻终于到来了,我已经忍耐很久了哦~虽然各种表达心意的行为之前我已经做过很多次了~但现在由指挥官这么认真严肃地向我表达心意……哎呀,我不就只能幸福到大脑一片混乱,任由指挥官摆布了吗?ようやくこの時が来たね。わたし、ずっと我慢してたんだ~。えへへ、前々からコクろうって思って色々してたけど、それより先に指揮官から真面目にコクられるなんてね~。……もう、幸せすぎて頭が真っ白。指揮官に好きにされちゃうしかないじゃない♡The time is finally here. I've been holding myself back for so long! Heehee. I've been pondering ways to pop the question, only for you to get to the finish line first! Gosh, I'm so happy I can't think straight. You'll just have to take the lead and do as you please♡

Ship Description放学之后为什么没回去?当然是在等指挥官接我回家啦~我可是等了很久哦?不过,也许可以趁现在没人……和指挥官玩点什么呢~放課後にどうして先に帰らなかったかって?もちろん指揮官が迎えに来るのを待ってたからよ~。すごーーく待ってたんだからね?えへへ、もうほかに誰もいないし……指揮官となにか楽しいことができちゃうかも~Why I didn't leave after classes were over? 'Cause I wanted to wait for you to come pick me up, duh! And I waited a looong time! Heehee, now that we're alone... maybe we could do something fun together!

'Cause I wanted to wait for you to come pick me up, duh! And I waited a looong time! Heehee, now that we're alone... maybe we could do something fun together!
Login指挥官可是让U-31等了好久~该惩罚一下指挥官帮我扇扇风什么的了。这里,有点热呢~もぉ、こんなに待たせるなんて~。罰として扇いでもらおうかな。だってここ、ちょっと暑いもんMaaan, you know how to keep a girl waiting! Make it up to me by fanning me. I wanna cool off a bit.
Main哎呀~指挥官看起来一脸疲惫呢,快让U-31帮你补充一下糖分吧,嘿——怎么样,很甜吧?あは♡指揮官ったらすごく疲れた顔してるね!糖分補給してあげよっか?そのまま口に、えい!どう?甘いでしょ?Ahah! You look like you're about to pass out! Want some candy to wake you up? Right in your mouth, like... this! Pretty sweet, huh?
Main 2总感觉房间里有点热呢~果然放学之后空调就关了吗?反正只有我们两个人,指挥官也不用一直穿着外套吧~なんだかここ、ちょっと暑いよね~。やっぱり授業が終わったらエアコンはオフにされちゃうのかしら…それより指揮官、今はわたしと二人っきりなんだし、ずっと上着を着てなくてもいいんじゃな~い?Man, it's kinda hot in here. I suppose they do they turn off the AC after classes are over... Anyhoo, it's just you and me now – you don't HAVE to keep your coat on, just so you know.
Main 3要不要猜猜U-31的棒棒糖是什么口味的~猜对了会有好事发生哦?哎呀……至于具体是什么好事……指挥官还真是喜欢明知故问呢~こっちのキャンディーの味も当ててみる?当たったら「いいこと」あるかもよ?あは♡……どんな「いいこと」かは……知らないフリしちゃって~Try and guess what flavor this candy is. Get it right, and I might give you a "treat." Ahah! Don't act like you don't know what I mean by "treat."
Touch唔……要我再挪个位置给你么?うぅ……ちょっとどいてあげようか?Mgh... Want me to shift over a bit?
Touch (Special)难道说这样的U-31对指挥官特别有吸引力~?この格好のわたしを気に入ったの?Do you like the way I look?
Touch (Headpat)嗯~呵呵~继续也可以哦。んん~、ふふ、続けてもいいよMmh! Heehee. Keep going if you wanna.
Return to Port这地上其实还蛮软的哦~指挥官累了的话,干脆就躺到U-31身边来吧~反正也不急着回去嘛。ここって居心地いいのよね~。指揮官も疲れてるなら、そのまま横になっちゃえば?別に急いで帰る必要ないでしょ?This is a cozy little spot. You oughta come lie down if you're feeling tired. There's no rush for us to get home, y'know.
Affinity (Love)我每天除了认真听课以外,还要赶走那些对指挥官图谋不轨的孩子呢,这可是很辛苦的哦~?所以在回去之前,指挥官就和我在这里多独处一会儿吧!就当做是对U-31的奖励,怎么样~?指揮官にヘンなことをしようとする悪い子たちを、毎日真面目に授業を受けながら追い払うのってかなり大変なのよ?だから帰る前くらいもうちょっとここで二人っきりでいてもいいでしょ?どうかな?わたしへのご褒美として♪It's not easy, chasing off naughty girls who wanna mess with you while also attending classes every day. I wanna stay here and relax for a bit before we head home. You don't mind, do you? Think of it as a reward for my hard work!

Login嗅嗅,嗅嗅——嗯哼~今天的指挥官身上也只有U-31的味道呢,看来没有遇到“危险”呢,这下放心咯~くんくん、くんくん――ふふ~ん、指揮官の体、今日もU-31の匂いしかしないのね。「危ないこと」に巻き込まれてないようでホッとした~*sniff sniff*... *sniff sniff*... Heheh. Once again, my odor is the only one I smell on you. Good to know you didn't get caught up in any "risky" business.
Main嗯~?贴身安保不就该紧紧贴在一起吗?就算走路不太方便也没办法呢~毕竟U-31要全方位保证指挥官的安全~ん~?身辺警護だからべったりくっつくのなんて当たり前じゃない?歩きづらくても我慢してね~。だってわたし、指揮官を全方向から守らなきゃならないんだから♪Hmm? Well, yeah, I'm clinging to you because I'm your bodyguard! If that makes it hard to walk, so be it! I've got to be ready to protect you from every which way♪
Main 2指挥官~我要突击检查一下你的手机里有没有被别人安装监听设备~嗯嗯嗯……好~壁纸设置成U-31和指挥官贴贴的自拍照啦!指揮官、抜き打ち検査よ!あなたの携帯に盗聴器が仕掛けられてないかチェックさせて~。うんうん……よし、指揮官とのツーショットの壁紙に設定完了っと!Commander, time for a surprise inspection! Let me check if your phone's been wiretapped. Alrighty... There, I set our selfie together as your wallpaper!
Main 3嘿嘿~指挥官,U-31已经把碍事的家伙都赶走了哦,快来抓紧时间抱一会吧~へへ~、指揮官、邪魔者はもう全部追い払ったよ。さあ、今のうちにぎゅっとして~Heehee. I've already sent all those ne'er-do-wells packing. Use this opportunity to give me a biiig hug!
Touch怎么啦指挥官~想要贴贴了吗~?どうしたの指揮官?ぎゅってしたいの~?What's up? Do you want a hug?
Touch (Special)呀~有、有种被电流击中的感觉……きゃ♡な、なんだか痺れちゃうね……Eek! G-gosh, THAT was exciting...
Touch (Headpat)哼哼~要再贴近一点吗?ふふ~ん、もっと近づいてもいいわよ?Heheh! Come closer if you wanna!
Return to Port欢迎回来,指挥官~躺下来好好恢复下精神吧~?放心,我不会让任何人来妨碍我……啊不是,来打扰指挥官的哦♪~おかえり指揮官~さあさあ横になって、元気になって?大丈夫。誰にもわたしを……じゃなくて、指揮官の邪魔をさせないんだから♪Welcome back, Commander. Go on and get comfortable. Don't worry, I'll make sure nobody interrupts me for– I mean, interrupts YOU for a while♪
Affinity (Love)指挥官指挥官~你喜欢纯牛奶还是巧克力牛奶呀?嗯~果然巧克力牛奶更好吧?像U-31一样的巧克力牛奶不仅色泽诱人,味道也充满层次呢~指挥官现在要尝尝看么~?指揮官指揮官~、ミルクはそのままかチョコミルクにするかだったら、どっちがいい?やっぱりチョコミルクだよね~?あは♡わたしと同じで、そそる見た目に複雑で奥深い…指揮官、味見してみる~?Hey, which would you choose between plain milk and chocolate milk? It's gotta be chocolate milk, right? Ahah! Chocolate milk is just like me – titillating, multi-layered, and rich... Do you want a taste?
