|This article is about a/an monstrous Rider in Kamen Rider Zi-O.|
Tsutomu Tsuzumiya is a childhood friend of Sougo Tokiwa. When he was a kid, he dreamed of becoming a great Oni like Kamen Rider Hibiki. Sougo mentioned that they both support each other's dreams.
However, on his current year, the dream seemed to be an illusion, and Heure forced him to have the power of an Oni by becoming Another Hibiki and going on a rampage. Sougo and Geiz confronted him until Todoroki came to aid. Before he was finished by Onigeki-Raiden Gekishin, an unknown projectile helped him to flee.
On the second round, Sougo and Geiz found out Tsutomu's identity after dealing him with their final blow. When they were about to have a talk, Heure stopped time and forced Tsutomu to transform again. When Sougo and Geiz were about to finish him off, Kyosuke interfered because he felt responsible about what happened to Tsutomu, his own pupil.

Behind the Scenes
His last name contains "Tsuzumi", a Japanese hand drum. Drum is also one of the original Hibiki's motif.
- His first name shares the same pronunciation with Tsutomu Tsumura, a former Oni disciple in Kamen Rider Hibiki.
- Another Hibiki is the last Another Rider/monster of the week introduced in the Heisei Era.
- Another Hibiki's name label oriented vertically might reference how the original series' logo was also vertically oriented with the words read from top to bottom, keeping in line with how Japanese is traditionally read vertically instead of horizontally.
- Like the Oni Riders, the logo of the Oni Riders retained in Another Hibiki’s belt.
- Like most Another Riders, Tsutomu as Another Hibiki is the opposite to the original Hibiki himself, as well as two of his disciples: Asumu Adachi and Kyosuke Kiriya:
- The original Hibiki is the oldest and most seasoned of all Oni, who has trained himself and worked hard to achieve greatness. Tsutomu was an in-training oni who was forced to take an easy way by becoming Another Hibiki.
- Asumu, being Hibiki's apprentice was a young man with a sense of humility and willingly decides to live a peaceful life as a doctor at the end of the series rather than being an Oni. Tsutomu outright voices his ambition of becoming an Oni and even bragged about his master.
- Both Kyosuke and Tsutomu have a lot in common, in addition to being ambitious, but are willing to take underhanded methods if they have to. Surprisingly enough, Kyosuke is aware of this in Zi-O, and as such he became much more matured and responsible than he was in Hibiki. Tsutomu, as Another Hibiki, however, is a twisted reflection of everything what Kyosuke was in the latter's home series.
