Tantei wa Mou, Shindeiru.

Similar art style. Overall very similar vibes in fight scenes and plotline. 

Both show have some kind of "the person is not dead although the body has changed" hence sometimes if may felt conflicting for us, especially when both MC loves the one who is "inside" the body of other people 

- both have female and male main character. - both of the female mc are genius - romance , mystery 

- long dialogues - sarcastic jokes if you like watching characters talking most of the time and characters telling jokes with a straight face, then this is for you.  

- Both have genius female detective main characters - Both have similar male sidekicks - Both have something more sinister going on, although not mentioned until later in Gosick  

both of them are of same genres mystery and if u like detective anime u will love both of them. 

Male mc goes through his regular life until he meets main female character who has some of romantic tension with the mc. One way or another they are together for years and their brief time together is part of the buildup of the 1 hour long 1st episode. Similar endings to their brief time together. The episode concludes with the opening song being played. By the second episode we see more female characters being introduced, some way or the other replacing the female heroine from the first episode. There are also some similarities between the character dynamics. Both siesta and ai hoshino are a little attached to the mc and are experts in their respective field of work and famous. Both kimihiko and aqua are kinda infatuated with the fmc and have a change in personality after their experiences with the character are over. They also eventually I'm some way attempt to follow in the footsteps of siesta/ai. Oshi no Ko and The Detective is Already Dead share somewhat similar plotlines; while twms takes a more realistic approach to the story, oshi no ko features more fantasy elements and reincarnation themes in it. read more
