About

An uneasy atmosphere grips Star Haven High School. Mysterious incidents targeting girls begin to unfold one after another, and rumors soon spread of things more suited to urban legends. And it is up to Beni Akesuzu as the head of the detective club to get to the bottom of these incidents.
But even she has a secret: she’s a secret agent for Bancho, a secret organisation specialising in dealing with the supernatural, and they know the truth. That real monsters lurk in the shadows, plotting to brainwash everyone in the school.
So far, Beni has narrowed her list of suspects, including both teachers and students. Now, it’s up to her and her friend, a fellow detective club member Nadeshiko to track down the culprits and solve the puzzle in a race to save the school and its students before it’s too late!

Investigate the eerie incidents that have occured at Star Haven high school. Explore the campus, gather clues, solve puzzles, and interact with a wide cast of characters to uncover the truth. And when the time comes, battle sinister foes with Beni’s unique skills and gadgets to protect everyone from the enemies hiding in the shadows!
Team up with Nadeshiko Shiratora, your loyal partner, as you navigate secrets, danger, and the weight of Beni's dual identities.
With unique battle challenges, a wide cast of characters, each with a story to tell, and an ever present mystery looming over all the students' heads, can you crack the case before it’s too late?














Explore the school grounds, gather clues, and interact with a wide cast of characters to unravel the mysteries that you come across.
Analyze the evidence you find to identify the suspects from the cast of characters you meet, each with unique backgrounds and potential motives.
Put everything on the line to protect the studnets of the school by engaging in unique challenges against the sinister entities lurking in the shadows once you have forced them into the light.

還可以 不過結局時留下了一堆懸念 為後續作品鋪路 每個章節雖說先是解謎探索 但基本上也沒啥謎題就是到處走而已 然後都可以失敗走一次壞路線 不用重來跑完可以直接在選一次走好路線 相當的方便整體玩起來還算舒服 好像還有個額外DLC這裡並沒有包含 可惜了希望以後可以補上 整體不錯值得推薦
I've already played a few games like this, so I was quite excited when I downloaded it and got to it right away. Did not disappoint. Even if this genre isn't to your liking, it's better to give it a try with an open mind. Just the other day I tried a western developer's game for the first time because it was recommended to me by a friend who couldn't stop raving about it. I was skeptical but I gave it a try and I liked it. It has plenty of different characters each with their own popular ACGN tropes and that's why it's not one of those games where it has just one or two characters you can root for, limiting the audience a preset niche. I tried Risty and the Village of Bocchino earlier, and this game reminded me of it. If you've played Risty before or something similar to it and you felt like you could use a bigger cast of delectable characters in a similar game, then Sirius will meet that demand perfectly. Games like these surely could use a sequel.
[h1]《特工·天狼星》简评[/h1] 本作是Lunarian(ルナリアン)社团在游戏方面的处女作,直接在DL上售出了1.45万份,算是小爆款,可见其制作小说的想象力放到游戏制作上也挺吃香的。 在红的带领下,侦探社近期在根据神秘获得的笔记对学校进行搜查,里面有先前蘑菇事件的怪人催眠诱导学生干坏事的信息,身为正义使者的主角团怎能坐以待毙,总结手中信息,8位嫌疑人浮出水面。少女们现在的首要任务是在学园变成怪人的天下之前,找出犯人并阻止他的野心。 游玩前需要先打上官网补丁。玩法以地图探索为主,收集信息,锁定嫌疑人并战胜为辅,没啥难度,主要是看剧情,里面的人物对话细腻,包含着不少信息。打赢有奖励,打输当然也有惩罚,如果输给了想要支配学园的怪人们,便会被怪人抓住洗脑,成为其爪牙并逐渐沉溺于涩涩,进入侍奉线。红的体质特殊,快乐污染度上升到一定程度的话,需要自慰来发泄,看着有着“最强”称号且正义感爆棚的特工红,也因快感而堕落,反差感拉满了。 通篇共有27个场景回想,无码,包含口交、手交、多P、扶她(出去)、阿黑颜等XP类型(里面的堕落类型能再进行深度探究就更好了),主角团都是妹子,所以自然也含有一些百合元素(这发色种类凑个彩虹不成问题),被怪人打败洗脑后将其余同伴奉献给怪人的设定也很有趣。CG色彩搭配流畅,表情很到位,汗气的加入恰到好处,这一套组合拳下来谁能顶住。游戏还附带DLC内容,推完正作还有额外小菜,这点确实不错。DL上的续作能早日端上来的话就更好了。 [quote] 游玩百态,将游玩心得用汉语化作玩家的指明灯,(๑•̀ㅂ•́)و✧ [url=https://store.steampowered.com/curator/35402408/]点击这里关注汉化语录~[/url] 如果喜欢这个评测,请点个赞让更多人看见 [/quote]
Been hyped for this game after hearing all the good things about it. Glad to say it didn't disappoint.
Awesome and unique game. I'm glad to see so many good reviews but confused why so many only have 2 hours of playtime. The after story alone took me a little over 2 hours and the main game took me nearly 10 hours to beat and see everything. Loved that the ending perfectly set up a sequel as well. Definitely worth a buy and the price is more than fair even without a sale.
不锁国区,需要补丁。一共5章,通关解锁全CG,不知道下一步就去医务室查看。游戏存在反派路线。
画风很喜欢,里面的角色很多,能满足很多人的XP,红毛、白毛、黑长直学生会长,真不错 主打的剧情和探索,但是也没有过于为难玩家,可以跳过一部分探索和关卡,失败后还可以开启无敌模式,很友好
Great mix of genres and the gameplay feels smooth. But honestly? With the patch, it becomes really hot and adds a great twist to the whole thing. Recommended 👍
题材比较猎奇——洗脑。游戏中人物们一步步堕入堕落深渊。有好坏多结局设定,但是官方应该是希望大家玩出坏结局。
