Learn Japanese with Anime - No One Can Tear Apart The Bond Between Nezuko And Me!

Analysis

俺 (noun) means “I” or “me” in a manly way.

と (connecting particle) means “and”, used to connect nouns.

禰󠄀豆子 (noun) is the name of his sister.

の (modifying particle) is used to add details to the following noun which is 絆 (noun) meaning “bonds” or “strong connections” between two or more people.

So 俺と禰󠄀豆子の絆 means “the bond between Nezuko and me”.

And は (topic particle) indicates the topic of the sentence.

誰も followed by verb negative form (〜ない/〜ません) means “no one does something”. For example, 誰も知らない meaning “No one knows”, 誰も否定しない meaning “No one denies”.

引き裂けない is the negative form of 引き裂ける which is the potential form of 引き裂く meaning “to tear apart”. So 誰も引き裂けない means “no one can tear apart”.

And the に particle is added for emphasis (NO ONE!). It can be used with verb negative & POTENTIAL form so you can’t say 誰にも知らない or 誰にも否定しない as the verbs are not potential.

Here are some examples,
誰もできない or 誰にもできない meaning “no one can do”
できない is the negative form of できる which is the potential form of する meaning “to do” so the に particle can be added for emphasis.

誰もわからない or 誰にもわからない meaning “no one can understand”
わからない is the negative form of わかる meaning “to understand” which itself has a sense of potentiality so the に particle can be added for emphasis.

Now I’ll also give you some tips about 絆 and 引き裂く.

絆 originally comes from ropes used to tie up animals and 引き裂く is the compound verb made up of 引く meaning “to pull” and 裂く meaning “to tear” or “separate”. So the image of 絆を引き裂く is like pulling apart a rope which connects two or more people.

Here are some examples with 絆:

固い絆 meaning “tight bond“
絆を結ぶ meaning “to tie a bond”
絆を強める meaning “to strengthen a bond”

And here are some examples with 引き裂く:

家族を引き裂く meaning “to tear a family apart”
心を引き裂く meaning “to tear one’s heart out”
手紙を引き裂く meaning “to tear up a letter”
