Pre-canon. How Fuuga came to part, and how Kazuki came to leave.
Saizou named him Prince of Terror. Kazuki never objected. It was true enough, and if some of the terror that had lodged in his bones for years seeped out to touch the people they fought, the ones who threatened even the tiny corner of life he had managed to cling to here… well, perhaps that would mean less for him which was all to the good as far as he was concerned.
Post Infinite Fortress arc. Kazuki takes care of Juubei while he recovers from their fight, and they find their way back to each other—even if Kazuki still can’t entirely admit his place in the relationship.
After the shouting was over and the rush of people had ebbed away again and all the wounded had been marched back to Gen’s back rooms by a frowning Ren, Kazuki had a chance to finally think about what he had found by returning to Mugenjou. He listened to the crunch and hush of medicines being mixed, to Ren scolding Emishi, to Sakura’s quiet as she sat beside Juubei, and hoped that this time he and Juubei could say what they meant, to each other, and not what they feared.
After the Kami no Kijitsu arc, Juubei brings Toshiki home to Kazuki and the three of them fit themselves together with a little more honesty and understanding this time.
"Do you object?" Kazuki murmured, knowing eyes holding his, and Toshiki flinched under that question, reminded now of exactly why he had followed Kazuki so long. That one question was everything he had tried to take by force from Kazuki, everything Kazuki had no need to force from him, laid bare as a drawn blade between them. He closed his eyes.
Toshiki needs evidence that he’s wanted and welcome by the one who brought him back to Kazuki.
Toshiki knew what he wanted; he just didn’t know how to ask for it.
Kazuki tops Juubei, which is a new experience for Juubei though not an unwelcome one.
Juubei was puzzled.
Moreover, he was puzzled by Kazuki, which didn’t usually happen. Well, hadn’t happened in years at any rate. And had certainly never happened in bed.
Saizou has been watching Kazuki and the others only from a distance, and Kazuki finally corners him and convinces him that his proper place is with them again.
Kazuki felt a stray breeze brush his cheek and sighed. Saizou seemed determined to be the most troublesome one of all for him.
Juubei had been the first to detect him shadowing them, never coming close, only watching, but never leaving them. Kazuki had tried, once or twice, to drift closer, but every time Saizou slid away. Thinking about it, Kazuki didn’t suppose he was actually surprised.
Fuuga celebrates Spring and the new year together.
He’d had to threaten Juubei with a celebration at home, with Juubei playing the Oni, before he agreed, but once they were in the middle of the laughing, shoving, shrieking crowd Juubei lost his stiffness and shoved back with a will. Kazuki laughed as much at that as at the scramble for thrown candies.
Post canon. Kazuki wants to build a relationship with Yohan. Yohan wants to find a new way forward for his clan. Saizou wants to escape the fear of his years with Yohan. And his sister wants everyone to be reasonable for a change. Contains spoilers for Saizou’s backstory in vol. 33 and Yohan’s in vol. 36.
Kazuki didn’t think it was his imagination that this spring was more beautiful than any he remembered. Circumstances might be adding shine to the season, to the faces around him that looked up at the clearing light and the drifting petals, but they were circumstances everyone shared, that everyone felt even if they didn’t quite know the reason. He wondered a little whether Yohan let the seasons of the Beltline turn, let himself see and feel this.
He wondered things like that a lot these days.
Something that might have happened the second time Kazuki goes to visit Yohan, as both Juubei and Saizou are wound up over the fact. Saizou discovers a very useful way to distract Juubei and himself.
Saizou wanted to pace. Unfortunately Juubei was already taking up most of the room.
