Bocchi the Rock Side Story Manga Is Great for Kikuri Hiroi Fans

Kikuri Hiroi can be one of those scene-stealing characters in both the Bocchi the Rock anime and manga adaptations. While the series tends to focus on Kessoku Band like Hitori, Ikuyo, Nijika, and Ryo, this funny and flawed ing cast member with moments of depth is a standout too. Though since she is an alcoholic and has plenty of vices, the enjoyment someone gets out of the Bocchi the Rock! Side Story: Kikuri Hiroi’s Heavy-Drinking Diary spin-off manga will vary depending on how much you like her and the original series.

Editors Note: There will be some mild spoilers for early parts of volume 1 of the Bocchi the Rock! Side Story: Kikuri Hiroi’s Heavy-Drinking Diary manga. 

While the original Bocchi the Rock is a four-koma series that gradually builds on the story of Kessoku band in strips that also can sometimes stand on their own, the Bocchi the Rock! Side Story: Kikuri Hiroi’s Heavy-Drinking Diary side story manga follows a more traditional format as it looks at Sick Hack’s singer and bass player. While it starts by bringing up Kikuri’s talents and how adept bandmates Eliza Shimizu and Shima Iwashita are, it also quickly establishes she is no angel and shows a copy trying to reason with her when she’s in a full drunken “incorrigible alcoholic”moment. 

It’s a stark introduction to two facets of her personality, and the first chapter continues to emphasize that. She gets so drunk after a sold-out Yokohama Arena show that she winds up blackout drunk in Kanazawa. While Eliza and Shima clearly respect her talents enough to perform and be in Sick Hack with her, neither is going to come and pick her up and they also definitely knew she probably wouldn’t make the fireworks show they were going to go to. People in the bar she winds up in think she’s exaggerating about her indie band being popular and talents, due to the fact she walks in drunk and keeps drinking. But then actual fans recognize her, ask to meet her, and her story. Kikuri gets carried away and offers to cover folks’ tabs, blowing through her money and winding up alone and broke at a shrine with a stray cat and huge bottle of cheap booze. 

What I appreciate is that Bocchi the Rock! Side Story: Kikuri Hiroi’s Heavy-Drinking Diary sort of feels like a different type of slice-of-life manga. It’s still going through an indie rocker’s daily life. We get a different perspective. But it doesn’t lock the story into a comedic or dramatic tone, and it establishes that from the outset. Because while this chapter starts out funny, as we see her deal with her drunkenness, not being able to convince people for a ride, and come to with spending almost all of her money as she’s carried away on fan adoration, that quickly turns darker. By the end of the chapter, she’s entered her infamous Spiral of Happiness, which sees her dealing with any discomfort or pain by getting so drunk that she gets “happy” and numb. 

And we see this continue throughout this spin-off. Kikuri reaches a high point, usually a performance of sorts or something dealing with her talents resulting in a win for Sick Hack or her personally. But then something happens to swiftly bring her down. It could be recklessly spending money that could have ed her for a month or longer. Maybe it’s getting so carried away in the moment that she trashes expensive equipment that belonged to a club. While we see people around her, such as Eliza and even Shima, do care in their own ways and offer different sorts of s, there’s a constant cycle that makes it both occasionally amusing and a fascinating analysis of her as a character. However, because Kikuri is a drunk, I could see it being painful or difficult for some people to read, especially when it can seem like she isn’t thinking about consequences or considering others.

So if someone really likes the original series or is interested in the character, I feel like the Bocchi the Rock! Side Story: Kikuri Hiroi’s Heavy-Drinking Diary manga can be interesting supplemental reading. But if someone has experiencing being in a role like Shima or being around someone like that, I think it might be a difficult read. Especially when moments come up when Kikuri or other people do get serious.

Volume 1 of Bocchi the Rock! Side Story: Kikuri Hiroi’s Heavy-Drinking Diary is available now, and Yen Press will release volume 2 of the manga on September 23, 2025. The company also handles the Bocchi the Rock manga. The anime is streaming on Crunchyroll.
