Sakuya Hishigata (菱形 サクヤ) is Sakuya Tachibana's incarnation from Kamen Rider Decade.

Fictional character biography

He is a Rank Ace senior employee of BOARD who has the ability to transform into Kamen Rider Garren with the sealed Stag Undead After Kazuma 's demotion, he starts treating him badly until he himself got demoted after losing his Rider System to Chalice. His life energy is then used by Hajime to create the Joker card.

World of the Rider War

Garren later appears in the World of the Rider War fighting with his fellow Kamen Riders from the World of Blade against the Riders from the World of Kiva, though it is unclear whether Hishigata survived the incident in his world or if a new Garren was chosen. This Garren later appears by Kazuma's side when he comes to help Decade crash the wedding of Apollo Geist and the Thorn Fangire, destroying the Undead and Fangire who had joined Dai-Shocker. Garren eventually disintegrates together with Kazuma in the aftermath of Super Apollo Geist's merging of the Rider Worlds. Rider War: Prologue Though not seen again, Garren was presumably restored along with Kazuma and all the other Kamen Riders in the Rider War after Decade was killed by Natsumi as Kamen Rider Kiva-la.

Kamen Rider Garren

"Turn Up!"
―Transformation announcement[src]

Just like the original Garren, he harnesses the Stag Undead DNA from the ♦A: "Change Stag" Rouse Card, utilizing the Garren Buckle Rider System to fuse with the Stag Undead's DNA.

  • Height: 200cm
  • Weight: 104kg

Ability Perimeters

  • Punching Power: 2.6t, 260AP
  • Kicking Power: 4.5t, 450AP
  • Maximum Running Speed: 100m/5.4s

Ace Form (エスフォオム Esu Foomu) is the default transformation of all Rider Systems. Rider System-01 harnesses the DNA of the Stag Undead sealed within the A: "Change Stag" Rouse Card and fuses that DNA with Sakuya Hishigata via the Garren Buckle Rider System, transforming him into Kamen Rider Garren. This Rider form has no distinguishing capabilities or attributes apart from any other Rider except its gunslinger-oriented design; its ability to modify its capabilities with Rouse Cards is the only note worth mentioning.

Hishigata was only shown to only possess an Ace form in the Kamen Rider Decade TV series.
