Sherliam isn't canon.
I have seen a lot of people claiming that Sherliam is canon based on Sherlock's updated official profile. So, as promised, I am going to debunk it.
1. Poor translation is not valid evidence.
The main argument I have seen has been used is the translation of Sherlock's Japanese profile down below (the picture attached). This phrase was translated by using Google Translate, which is a translation tool that is well known to be often unreliable, especially with complex or culturally rich phrases such as this japanese phrase.
I can guarantee you that everybody who claims it's canon is not a japanese speaker. Japanese speakers have said it themselves that the phrase "友情以上の絆" does not mean it is romantical. Unlike the poor translation in the attached photo, the proper translation of the phrase is "he feels more than friendship." Now, I understand "more than friendship" can be interpreted romantically in some languages, however it's important to remember that in Japanese, this phrase can describe close relationships between people that are not limited to romantic attraction. It can also refer to relationships that are rooted in shared experiences, respect, or even rivalry, especially in contexts involving mentorship, teamwork, or philosophical debates. The use of such language in this context is not a clear declaration of romantic intent but rather a reflection of the complexity and depth of Sherlock and William’s connection, which remains fundamentally non-romantic. Therefore, using this phrase to argue for a romantic relationship is irrational.
2. Homosexuality in the victorian era.
Let's not forget, MTP is set in the late 19th century, a time when LGBTQ+ relationships were socially unacceptable and rarely depicted. Based on what the anime was inspired by, I can't recall such themes being presented. Meaning, despite some historically inaccuracy in the manga, it is unlikely to be shown as acceptable in the series.
3. Character's profile.
I think that if they were canon, William's profile would also mention Sherlock in a somewhat romantic manner. Furthermore, I haven't seen anyone mentioning Watson's profile. He is described as Sherlock’s “companion both in his professional and private life, and his only true confidant.” You view this as friendship, but when it comes to William, it has to be romantic? Alright.
Some of you keep forgetting the plot and the intent of the creator, which is really upsetting. MTP explores many important themes, yet people overlook them and call it a BL or some other nonsense.
As you can see, Sherliam, let alone other ships in the manga, isn't canon. I hope this cleared it up a bit, and my arguments were logical enough. I apologize for not posting this earlier; I was busy with exams and work.
