The Harinezumi Halfbody (ハリネズミハーフボディ, Harinezumi Hāfubodi, lit. Hedgehog Halfbody) is a biotic A-Side Halfbody of Kamen Rider Build. Accessed through the Harinezumi Fullbottle, its Best Match is the Syoubousya Halfbody.

In any form that uses the Harinezumi Fullbottle, Build is armed with the Spine Knuckle (スパインナックル, Supain Nakkuru) on his right fist, allowing him to clobber or punch foes with spikes that extend outwards when used. When first used after transforming, the spines notably appear to fly in from the surroundings to the Spine Knuckle, only extending from it on subsequent attacks.

Design/Powers

• Sting Head Armor (スティングヘッドアーマー, Sutingu Heddo Āmā) - The white head armor. Its surface is covered with hard and fine thorns, enhancing its defensive ability.
• Left Eye Hedgehog (レフトアイヘッジホッグ, Refuto Ai Hejjihoggu) - The left eye. Reaction speed and accuracy of searching for enemies during battle have been improved. Additionally, a special olfactory sensor is installed, allowing the user to find enemies hiding underground.
• Needle Face Module (ニードルフェイスモジュール, Nīdoru Feisu Mojūru) - The 'porcupine spines' on the left eye. It is an armed strengthening device that can control the shape of the Hedge Needles (ヘッジニードル, Hejji Nīdoru) located on the whole body, strengthening them to harder, sharper and easier-to-pierce states.
• BLD Signal (BLDシグナル, BLD Shigunaru) - A data collection device located on the forehead area. It not only collects combat data, but also performs emergency repairs on the body when necessary. Additionally, it can project any information holographically.

• BLD Spine Shoulder (BLDスパインショルダー, BLD Supain Shorudā) - The right shoulder armor. When receiving an enemy's attack, the user can deal counter damage with the thorns on the surface.
• Spike Rush Arm (スパイクラッシュアーム, Supaiku Rasshu Āmu) - The right arm. It is highly flexible and by swinging it around and allowing the fist to make contact with opponents, specializing in morning star attacks.
• BLD Spine Knuckle (BLDスパインナックル, BLD Supain Nakkuru) - The spiked glove. It is tough and covered with stretchable thorns. Impact from it can cause great damage to an enemy's armor and internal functions.
• BLD Unlimited Suit (BLDアンリミテッドスーツ, BLD Anrimiteddo Sūtsu) - The shock-resistant bodysuit. Along with protecting the wearer’s body, there is a limiter installed that can be released to bring out full physical ability.
• Spike Rush Leg (スパイクラッシュレッグ, Supaiku Rasshu Reggu) - The left leg. It has excellent defensive ability and can scrape off enemy armor by using the fine thorns on its surface.
• Urchin Foot Shoe (アーチンフットシューズ, Āchin Futto Shūzu) - The left foot. It specializes in fine footwork and can quickly shorten the distance to an enemy. It is also possible to sharpen the toe section like a needle and launch a sharp kick attack.
