Description
Tennōji Shidō, a third-year student at Tottori Hakurou High School, captains its sumo club. His younger sister, Saki Tennoji, acts as his manager. Lacking any family history in sumo, Tennōji credits his achievements entirely to relentless hard work and profound passion for the sport. Though relatively small-statured as a child, he underwent a dramatic growth spurt in middle school, ultimately reaching 188 cm in height and 139 kg in weight. This physical transformation propelled him to dominate high school sumo, securing the prestigious title of High School Yokozuna in individual bouts during both his first and second years. He further cemented his dominance by winning the All-Japan Championship twice, in his second and third years.

Physically, Tennōji possesses sharp blue eyes and wild blue-black hair. His naturally positioned eyebrows sit close to his eyelid folds, rendering them less visible. He competes in Tottori Hakurou High School's dark blue mawashi, distinguished by a single red stripe on the left side. Outside the ring, he is often seen with a white jacket draped casually over his shoulders.

Tennōji's personality merges humility with fierce competitiveness. Easygoing and approachable in daily life, especially around his sister, he transforms into a figure of demon-like focus during matches. He holds deep respect for sumo's traditions and his opponents, meticulously studying match footage to visualize every possible outcome, including his own defeats. This analytical method stems from his conviction that loving sumo more than anyone else and rigorous training are the true foundations of strength. He speaks in the distinctive Kansai dialect, frequently using phrases like "ya" and "yarou". Having once faced similar physical limitations, Tennōji feels a kinship with smaller wrestlers like Hinomaru Ushio. His personal hobbies include Googling himself, watching horror movies, and scrutinizing opponents' social media for tactical advantages.

In combat, Tennōji wields a potent combination of imposing size, surprising agility, and sharp intellect. His signature technique, the Six Points Torso Slice, immobilizes opponents by locking six critical pressure points (arm, wrist, elbow, head, neck, and hip) to set up an armlock hip toss. Against less challenging opponents, he often employs a straightforward jaw-gripping shove. He demonstrates adaptability by incorporating opponents' techniques, such as Hinomaru's Demon Wheel, into his own countermeasures. His fighting style splits into two distinct forms: a calculated, defensive mode focused on avoiding losses, and an erratic, offensive barrage specifically developed to counter tactical wrestlers like Mizuki Sada. His significant reach advantage allows him to deliver powerful forearm charges while maintaining an upright stance, effectively neutralizing low-leverage attacks.

Key battles shaped his journey. Tennōji remained undefeated until the Inter High individual tournament, where he finally fell to Sōsuke Kuze after a clash of techniques culminated in Kuze forcing him out of the ring. During the team tournament semifinals, he faced Hinomaru Ushio once more. Despite anticipating Hinomaru's strategies, Tennōji was overwhelmed by a blend of defensive maneuvering and hybrid techniques borrowed from Hinomaru's teammates. Though disappointing, this loss solidified his respect for Hinomaru's adaptability. He later faced Hinomaru again in the All-Japan National Championships, defeating him to win the tournament and securing a #15 ranking in the professional makushita division.

He bears the epithet "Dōjikiri Yasutsuna," referencing one of Japan's legendary "Five Swords Under Heaven," symbolizing his status as a national sumo treasure. Tennōji ranks fourth in the series' popularity polls.
