do you really think that kazuha’s story quest being about the whole “i’d rather see him recognise and atone for his mistakes that see him punished for them” was a coincidence? or how we were helping kazuha put together bits and pieces about his ancestry? or how scara spared kazuha's relative during the fall of the raiden gokaden upon noticing kaedehara yoshinori’s appearance and his connection to the niwa clan? niwa whom scara called: my family… my friend.

kazuha wouldn’t hate scaramouche because accepting the past and moving on is such an important part of his character. in his story quest he says: "but to make this arduous journey, you committed countless atrocities, and showed a blatant disregard for human life. even if you were to sever that divine light, is this truly the outcome your maker would have desired? […] this person (blade) has committed unforgivable atrocities but only because it lost its original master. no one was there to correct its errors when it was losing its way." tell me this could not easily be applied to scara. kazuha has demonstrated this incredible capacity for forgiveness countless time. (for example: his voice line about raiden; “do i simply resent the raiden shogun because of what happened in that duel? […] i’ve thought about this a good long time, and i believe the answer is no.” and later on he only talks about his “dissatisfaction” with her. he never uses the word hate.)

when kazuha found out what happened during the fall of the raiden gokaden he said: “knowing the truth behind what happened is enough for me, […] that being said, if the enemy from all those years ago is still lurking and plotting to stir up more trouble, then i definitely won’t turn a blind eye.” — while he put what happened in the past behind him, if kunikuzushi/scara were to pose a threat in the present kazuha would act because he believes that: “what’s most important for each person is not the past, but the present.”

at first i thought it was just a story about a samurai and kamai and how humans and youkai can be friends. a story about a friendship of a mortal and an immortal — a friendship that is inevitably going to come to an end. “lord kamai’s appearance hasn’t changed, but his dear friend in front of him had grown old. the joys of friendship gradually gave way to the pain of regret. people meet, become friends, and then go their separate ways.“

however, miko says that is not the full story. “that samurai’s name was yanagibashi takuto, who also happens to be the founder of the souran isshin art.” so, this was also the story about how the souran isshin art came to be.

now, how does this connect to kazuscara? i think takuto can easily be compared to niwa in this case, a human who forms a bond with an immortal, who in this case would be scara. and their friendship meets a similar end: niwa dies while scara continues to live — “the joys of friendship gradually gave way to the pain of regret.” however, miko continues: “the bond formed by friendship will not be broken, but rather, carried on in a new form.” and we know that kamai later on came to befriend the third-generation heir of the souran isshin art. so what does this mean in scara’s case? he might have lost niwa, his friend and family, but their bond will carry on in a new form. and that form is kazuha.

so in conclusion, i believe this story might have been foreshadowing of their future meeting and friendship.
