Tōgo Asagaki, alias Kizuna Red, faced early tragedy with his parents' deaths, leading to adoption by his father's friend Daigo Shindo. Joining the Shindo family introduced step-siblings Kiyohiro and Sumika, sparking Kiyohiro's resentment over perceived favoritism. At eighteen, Tōgo intervened in a monster attack during high school, becoming Earth's red warrior for the Bansou Sentai Kizuna Five. He battled the Relationship Enders under the Breakup King until sacrificing his life in their final clash, triggering reincarnation into a fantasy world with his sentai powers intact. Hot-blooded and optimistic, Tōgo champions justice and bonds, often radiating cheerfulness while rarely angering. Yet childhood loss and Tenri Nikaido's death—Kizuna Silver and his unrequited love—left deep trauma. This fuels an abandonment fear and compulsive protectiveness, sometimes igniting the berserk Kizuna Black state where he attacks indiscriminately. Despite impulsive acts like explosive transformations or cultural misunderstandings, he displays surprising emotional intelligence in conflict mediation. He avoids injections and collects shokugan toys. As a B-rank adventurer in the fantasy realm, he aids others while seeking a path home. He dueled mage Yihdra Avom after mistaking her golem for a threat, forging a partnership where she studies his powers. Their bond evolved into mutual romance and physical intimacy. Later, he joined Princess Teltina Liz Wagrel Alvarost's mission against demonic mana seeds, overcoming knight Lowji Mist's hostility through combat. Their rivalry shifted to grudging teamwork. He also aided Sun Elf Raniya Amen in rescuing her lover Azir and mediated clashes between Yihdra and the enigmatic Shau’ha Shemhazar. Tōgo transforms into Kizuna Red for superhuman combat abilities, wielding bandage-themed arms like Cooperation Caliber swords and the Marriage Beam Gun. Mobility gear includes the Turbo Huddle, while signature moves encompass the Bond Bind restraint and Burning Kizuna Punch finisher. Emotional bonds summon his mecha, Maximum Kizuna Kaiser. Trauma-triggered Kizuna Black amplifies power but erodes control—until Yihdra helps him master this state during a mana seed crisis, unlocking the stabilized Burning Blood form. Additional traits include foresight immunity via Tenri's spiritual protection and culinary skill from heightened taste perception. His development revolves around trauma confrontation. Guilt over Tenri's death worsened his Kizuna Black instability until Yihdra's love confession during an episode allowed positive emotion channeling. He reconciled with Kiyohiro after the latter's brainwashing as Bondkiller and embraced his new-world role without abandoning past bonds. Flashbacks trace his growth from orphan to sentai hero valuing connections, with his reincarnation journey cementing cross-world justice commitments.
