Aloof Ally: All of the Touken Danshi in this team are fairly level-headed and aren't particularly close, despite quite a few of them being from branches of the same schools. They were simply put on the same team and work together.
This trope becomes especially egregious in the Ichigo Hitofuri vs his shadow forgery plot, as none of the swords seem to be bothered all that much about what's happening to Ichigo even though his life as a Touken Danshi is on the line, and in the end, only Hasebe makes an effort to encourage Ichigo to fight harder to save himself from disappearing.
Badass in Distress: Ichigo Hitofuri. As Kage begins to take over his identity as the sword of the same name, his own existence is called into question, and he begins to fade from reality with the other Touken Danshi not knowing what to do or how to help him. In the end, he ends up saving himself from distress by convincing Honami Kotoku of his legitimacy, who then tells Hideyoshi Toyotomi.
Canon Foreigner: "Kage" is a Touken Danshi unique to this continuity.
Clap Your Hands If You Believe: A large portion of the plays plot revolves around this trope, as a shadow forgery of Ichigo Hitofuri is able to replace him as the original for a time because people believed he was the real one after being chosen by the famous sword appraiser Honami Kotoku. The more people believed in him, the less real Ichigo Hitofuri became, losing his identity and even his colors until he resembled a black Palette Swap of himself and reverted back into tsukumogami form. He’s only saved when Honami Kotoku convinces Toyotomi Hideyoshi of his validity, which causes the real fake to return to his original form.
Cloudcuckoolander: Honami Kotoku, who believes he can hear the voices of Sword Tsukumogami due to the Historical Revisionists' influence on him. He acts borderline obsessed with the swords he takes care of, even lovingly caressing them when no one's around. His attitude as a child suggests that he was always a little strange even before the Historical Revisionists got to him, though, as he put saving a sword ahead of his own life. For all of his eccentricities, however, his love for swords is genuine, especially when compared to how Toyotomi treats them.
Connected All Along: This is the first time in the entire Touken Ranbu series, not just the musical, that Yamanbagiri Chougi, Koryuu Kagemitsu, and Daihannya Nagamitsu are acknowledged as being from the same school and are given interactions accordingly.
Evil Twin: Kage is this to Ichigo Hitofuri, although he may not be completely evil. He simply wants to exist and Ichigo stands in the way of that.
Hoist by Their Own Petard: The Historical Revisionists spend most of the play acting out an elaborate plan to replace the real Ichigo Hitofuri with "Kage" so that it can be on their side and help them change history by killing Hideyoshi Toyotomi. However, when Kage is fully converted, he instead defends Toyotomi and fights against the Historical Revisionists because he inherited the real Ichigo's loyalty to his former master. He still views the Touken Danshi as his enemies, however, especially since they oppose his existence as the real Ichigo.
Identical Twin ID Tag: It is easy to tell "Kage" Ichigo apart from the real one, even after he assumes his identity, because he has unkempt mint colored hair with black streaks, compared to Ichigo Hitofuri's tidier appearance.
Idiot Ball: Onimaru very nearly tells Hideyoshi Toyotomi his real name, despite knowing that he was owned by Toyotomi at the time and that revealing his identity as a Touken Danshi could jeopardize history. Thankfully, Hasebe and the others are able to stop him in time and come up with an alias for him.
Inseries Nickname: The fake Ichigo in this play is referred to as "Kage" by the Touken Danshi to distinguish him from the real one, with "Kage" derived from his status as a shadow forgery, kageuchi, or the real sword.
Killed Off for Real: Ichigo cuts down Kage near the ending of the play and the latter disappears, implying that he's gone for good.
Let's Split Up, Gang!: The team divides into two groups of three to gather information on the Historical Revisionists' plans, with Heshikiri Hasebe joining Koryuu Kagemitsu and Daihannya Nagamitsu while sending off Onimaru Kunitsuna, Ichigo Hitofuri, and Yamanbagiri Chougi.
Made of Iron: The newly manifested Kage won't stay down no matter how many times Chougi and Ichigo cut him. When Ichigo cuts him down in the ending, though, he goes down in one hit.
Mind Control: The Historical Revisionists' mind manipulations aren't limited to the human characters in the setting, as they begin to influence the Touken Danshi into thinking that the shadow forgery of Ichigo Hitofuri is the real one, making the fake Ichigo stronger.
Musicalis Interruptus: At the midpoint of the play, Ichigo Hitofuri randomly has a flashback to when he was burned during the Summer Siege of Osaka, which is turned into a song number. Yamanbagiri Chougi manages to snap him out of it mid-lyric, just in time for him to defend himself against the approaching Historical Revisionists.
Mythology Gag: Hasebe not liking being called "Heshikiri" is referenced in this play, although the reason is not explained and it's Played for Laughs since Chougi calls him "Heshikiri-kun" anyway, much to his annoyance.
Nice Guy: Even after stealing his identity and making multiple attempts on his life, Ichigo still claims Kage as his brother before he disappears.
Palette Swap: Kage is a black palette swap of Ichigo Hitofuri, at least until people begin to believe he is the real Ichigo. Then Ichigo himself begins to become the palette swap.
Princely Young Man: Ichigo Hitofuri, at least in his presentation. This reflects in his fighting style, as he wields his sword in a more refined and modern manner than most other swords.
Shown Their Work: There supposedly was a shadow forgery of Ichigo Hitofuri that existed at some point in history, which is the basis of this play.
Spot the Imposter: Becomes the plot about halfway through the play when the appearance of a shadow forgery of Ichigo Hitofuri finds its way to Hideyoshi Toyotomi due to Historical Revisionists interference.
What Happened to the Mouse?: Mikazuki doesn't meddle behind the scenes in this play despite the Historical Revisionists very nearly succeeding in erasing a fellow Touken Danshi from existence with their own meddling.
