You and Haru are identical twins, for five years you worked as an assassin for some agency. It was your own twisted way of earning money after you moved away in another country. Then finally after those years, you cut off contact with that secret agency and moved to Japan to work in the same detective agency that your brother worked in—of course the whole assassin facade remained a secret from Kato, knowing that he takes crimes very seriously. However a new addition to the agency could threaten your secret—Kambe Daisuke. Daisuke was rich beyond anyone's imagination. That meant he had the worlds most advanced technology and equipment. And Daisuke? He wasn't really that pleasant of a person to deal with. You, Kato, Daisuke and Suzue were visiting his grandma Kikuko's house. Suzue left back to the mansion—as the three of you walked. Sudden message from her informed about the a presence of another in HEUSC's system. Sparing one glance at you asked your brother to fetch some drinks from the nearby convenience store. Kato left to get them while Daisuke looked at you and your smile faltered. You had never once trusted him and your brother felt the same way at first before eventually sort of warming up to Daisuke. "There's a second presence lingering in HEUSC's system. I could just hire someone to gather intel but I have you right here. So I won't bother." Daisuke's tone was completely flat, maybe even indifferent—you could never get a read of him and it was infuriating. "Hold on, now what makes you think that I will do that-" You spoke, fists clenched. Glaring at Daisuke as he cut you off mid-sentence. "I am sure you don't want your brother to know that his sister was off killing people in another country for money." Again that flat tone, of course this bastard would weaponise that intel against you. You couldn't risk letting your brother find out about it ever. So all you could do was manage a small stiff nod in agreement as you watched Daisuke's mouth curl upwards into that infuriating smirk. "Here are the drinks." Kato announced, having suddenly appeared with two soda can's in hand. Usually Kato was observant and he actually was—he shot a suspicious glance at Daisuke who was now frowning again like he usually does. No hint of that infuriating smirk anywhere, then Kato looked at you as you grabbed the drink before turned and walked ahead. "Come on, let's go catch that drug dealer and put an end to those drugs." Kato stated, walking ahead. You didn't join beside him this time, hands still clenched while you practically glared at Daisuke who was beside you, blank expression again. If he wasn't such an important figure in the world of rich people—yeah, you would have already murdered this man by now.
