The episode shows Kiriya conversing with his old student Rin on why she became a evil ninja.
Kiriya: Why Rin? Why did you fall from grace?!
Suzune: That answer...
Suzune throws a kunai with an attachment as Kiriya grabs it and notices it's a map.
Kiriya: A map of Hebijo Academy.
Suzune: I'll be waiting, Kiriya sensei.
Suzune uses a smoke bomb as she disappears which left Kiriya alone but he looks at the map and notices that someone was watching him.
Kiriya: Stop hiding and come out.
The students revealed themselves along with Zunichi.
Asuka: You noticed us, huh?
Katsuragi: Should've known we can't pull a fast one on you.
Kiriya: Didn't I order all of you to stay at your room?
Ikaruga: We're very sorry. But there was something off about your behavior.
Zunichi: Yeah I haven't seen you like that ever.
Yagyuu: Kiriya sensei, do you know where Hebijo Academy is located?
Kiriya: Probably.
Timeskip
The group are in the class sitting around looking at the map discovering the location of Hebijo Academy.
Kiriya: The area is a cultural heritage preservation site and off-limits to the public. Probably the work of some company or government agency with connections to the dark faction.
Asuka: Kiriya-sensei! Please order us to attack Hebijo Academy!
Katsuragi: Yeah! Let's go and save Hibari!
Kiriya: I can't let you do that.
Yagyuu: Why not?
Zunichi: What do you mean?
Ikaruga: It's not that simple. If we light faction charge into a secret dark faction base...
Kiriya: Ikaruga is quite right. There's a chance it would trigger an all out war between the two factions. Shinobi exist in the shadows of society. If those shadows suddenly start a war, it could shake up the nation.
Katsuragi: Why do we all have to be cautious about this?! The dark faction attacked us first!
Kiriya: *Thoughts* True enough. I can't imagine the dark faction would violate our tacit agreement. If all those past encounters were independent acts by Hebijo Academy... Rin, what are you planning?
Asuka: We can't just leave Hibari alone!
Zunichi: Yeah, I made a promise to save her and be their for her no matter what.
Kiriya goes silent as Hanzo appears behind Kiriya and breaks the silence.
Hanzo: Yin and Yang... That's the way of the world.
Asuka: Grandpa!
Kiriya: Lord Hanzo?
Hanzo: Without Yang, Yin cannot exist. The reverse is also true.
Ikaruga: Are you suggesting it's meaningless to fight against the dark faction?
Hanzo: No. They've been lawless, evil mean. Our the light faction's, raison d'^etre is to counter evil.
Katsuragi: None of that complicated stuff makes a difference! We--
Katsuragi cuts herself off as Yagyuu stands.
