Mc has death note as his cheat/golden finger. The mc is very smart and uses his death very well. He acts like death from Final Destination movies where he micromanipulates little things to make each death seem like an accident. He joins the Black Organization and is operating as an agent and rises through the rank there. The mc is also very cunning as outside he is seen as a gentle person and a famous detective in the belka city while being a high ranking officer of the black organization. He is also a famous mystery novel author. The mc doesnt strictly follows all adventures of conan but instead has his owns events. There are only a couple of chapters that involves cases involving the original. The harem is tolerable he does not chases after every girl he sees but chooses them very well and properly cultivate their feelings. Some interactions are even wholesome especially with Ran and Haibara Ai/Sherry.

5 star very good interesting world hopping and good choice of worlds. Only flaw is the very abrupt ending and no explanation about what happened after the end battle with imu and what happened in danmachi who did he marry and who are his children. That's the only flaw otherwise very good 👍
