Early life

After watching a pro-wrestling video while still in elementary school, he became inspired by Keiji Muto. While in third year of junior high, he learnt about Triple H attempting to recover from a serious quad injury, and was so impressed he decided to become a pro-wrestler. To supplement this, he attended a Taekwondo Dojo while attending Kumamoto Prefectural High School and learnt various techniques. Yoshioka attended Okayama University as it was close to the Wrestle Gate dojo in Hiroshima, and after one unsuccessful attempt, was entered into the college on his second attempt. He started in April 2007 and studied at their Faculty of Pharmaceutical Sciences for 6 years, earning a qualification as a pharmacist.

Professional wrestling career

Wrestle Gate (2007-2013)

A day after starting at university, Yoshioka began training at Wrestle Gate, run by Hanzo, and would train there whilst also attending school. After nearly a year, Yoshioka was given exhibition matches on Wrestle Gate pre-shows, whilst wearing a mask, On October 5, 2008, he made his official debut teaming with Susumu in a losing effort against Kindaichi Hogo & Minoru Fujita on Wrestle Gate's 5th Anniversary show. Eventually, he changed his ring name to just Seiki (stylized in all capital letters).

In 2011, Seiki won his first belt, winning the Hakata Tag Team Championship (a championship managed by Pro Wrestling Kageki) with Susumu, in a team known as ''Scramble☆Time''. They successfully defended the belts 3 times before losing them to Hanzo & Victory Shanghai. During this time, when All Japan Pro Wrestling (AJPW), DDT Pro-Wrestling (DDT) & Wrestling New Classic (WNC) were in Hiroshima & Okayama, Seiki would occasionally perform on their shows.

Seiki unsuccessfully challenged for the Hakata Light Heavyweight Championship (held by Cosmo Soldier) twice in 2012 while spending that year wrestling his final matches for Wrestle Gate & Pro Wrestling Kageki.

All Japan Pro-Wrestling (2013, 2019)

In April 2013, after finishing his pharmacist degree, Seiki decided to start wrestling full-time in Tokyo and graduate from Wrestle Gate in Hiroshima. He wrestled his farewell match on May 26, 2013, teaming with Betcha Hogo in a winning effort against Daisuke Masaoka & Yuki Tanaka. He was signed by All Japan Pro-Wrestling on May 1 as Seiki's trainer, Hanzo, is close with Kaz Hayashi who was a senior figure there at the time. Seiki then again started going by his real name Seiki Yoshioka and begun retraining for AJPW.

After only making sporadic appearances since signing with Wrestle-1, Yoshioka wrestled his first full tour in 5 years by participating in the Junior Battle of Glory 2019. Yoshioka finished the league with a record of 3 wins, 1 loss and a draw, advancing to the final, where he was defeated by Koji Iwamoto.

Wrestle-1 (2013-2020)

In 2013, there was a mass exodus from All Japan Pro-Wrestling after issues with its new ownership, and Yoshioka was one of the many that joined Keiji Muto's new promotion, Wrestle-1 (W-1), He left AJPW on June 30 and transferred to W-1 on July 10. He resumed his re-training, and debuted against Hiroshi Yamato on September 15 in a losing effort.

Yoshioka's first big win came in January 2014 when he pinned Kaz Hayashi in a singles match in just over 6 minutes after a ''Swanton bomb''. On March 2, he and Manabu Soya defeated Ryoji Sai & Kazma Sakamoto in Ryōgoku Kokugikan in an event co-promoted by partner company Total Nonstop Action (TNA). Later that month, Yoshioka won a battle royal to face Seiya Sanada for the TNA X-Division Championship. He would go on to unsuccessfully challenge for the title in a Korakuen Hall main event after Sanada pinned him following a ''Rounding Body Press''.

On November 7 on ''Kassen ~ Battle Zero1vsW-1 Full Battle~'' in Shinjuku Face, Yoshioka won Pro Wrestling Zero1 (Zero1)'s NWA International Lightweight Tag Team Championship with Shuji Kondo from Takuya Sugawara and "brother" Yasshi, after Yoshioka pinned Sugawara. Yoshioka entered W-1's ''First Tag League'' with Minoru Tanaka, but failed to win the tournament. After one successful defence, Yoshioka & Kondo lost their belts back to Sugawara and Yasshi. After two straight unsuccessful challenges for Minoru Tanaka's Wrestle-1 Cruiser Division Championship, he started teaming with Jiro 'Ikemen' Kushio. This alliance eventually came to include Yasufumi Nakanoue, and the three became known as ''Jackets'', as all three men wore jackets during their matches. They won the UWA World Trios Championship from ''New Wild Order'' ( Akira, Jun Kasai & Kumagoro) on October 9, 2015, at ''Wrestle-1 Tour 2015 Fan Appreciation Day'' in Korakuen Hall.

Yoshioka unsuccessfully challenged Andy Wu for the Wrestle-1 Cruiserweight Championship on December 24.

On January 7, ''Jackets'' would vacate their UWA World Trios belts after Yoshioka couldn't make their next scheduled defence due to cecum surgery.

On April 28, Yoshioka would team with Nakanoue to challenge ''Real Desperado'' (Yuji Hino & Kazma Sakamoto) for their Wrestle-1 Tag Team Championship, but were unsuccessful after Yoshioka was pinned by Hino following a '' Fucking Bomb.'' In June, Nakanoue left Wrestle-1, and this led to ''Jackets'' disbanding. Their last match together was against ''Real Desperado'' (Yuji Hino, Kazma Sakamoto & Nosawa Rongai), with Nakanoue pinning Nosawa after a Diving Elbow Drop for the win. In July, Yoshioka would team up with Andy Wu & Daiki Inaba to win the UWA World Trios titles back from Hayashi, Tanaka & Tajiri at ''Wrestle-1 Tour 2016 Symbol'' in Shinjuku Face. This time, Yoshioka's team managed a successful defence, defending against Kai, Hiroki Murase & Shota. Yoshioka would defeat teammate Andy Wu in a Cruiserweight Championship #1 contender's match, and on September 18, challenged Yusuke Kodama in a losing effort.

Yoshioka defended his Cruiser Division title against Alejandro on April 18, marking his fourth defense. The next day, ''Newera'' disbanded. On June 13, Yoshioka lost his championship to former ally Yusuke Kodama who had recently just joined ''Enfants Terribles''. This brought his reign to 9 months with 4 defences. In September, Yoshioka failed to regain the Cruiser Division Championship from Kodoma. Yoshioka suffered an injury that month on a J-Stage show and missed 2 months of action. Before his return, it was revealed by the ''#Stronghearts'' stable led by Cima that they had a 'spy' on Wrestle-1's roster that would join them.

He returned to the ring on June 9 teaming with ''#Stronghearts'' to take on Wrestle-1's Home Team. ''#Stronghearts'' lost the match. Yoshioka teamed with El Lindaman in the Wrestle-1 Tag League 2019, finishing the league with a record of 1-1-1.

On April 18, Yoshioka appeared at Pro Wrestling Noah, as the newest member of Takashi Sugiura's Sugiura-gun after being recruited by Nosawa Rongai. He then pinned Daisuke Harada in a six-man tag team match. He teamed up with Sugiura-gun member Hajime Ohara to challenge ''Ratel's'' (Hayata & Yo-Hey) for the GHC Junior Heavyweight Tag Team Championship the next day, but they were unsuccessful.

In that match, Yoshioka was eliminated first. On May 10, after ''Stinger'' (Atsushi Kotoge & Kotaro Suzuki) defeated Yoshioka & Ohara, Kotoge betrayed Suzuki, and wished to join Sugiura-gun. Nosawa Rongai then came out and disallowed it, saying he didn't trust him. This led to Yoshioka, Ohara & Kotoge turning on Nosawa, forming their own stable, which became known as ''Full Throttle''. On August 30, at ''Kawasaki,Go!'' Yoshioka unsuccessfully challenged Kotaro Suzuki for the GHC Junior Heavyweight Championship. On September 23, Yo-Hey turned on Daisuke Harada, and Atsushi Kotoge defended his old friend, reuniting ''Momo no Seishun Tag.''This caused Ohara & Yoshioka to kick Kotoge, their leader, out of ''Full Throttle'', and welcome Yo-Hey as their newest member.

After the match, he said that he was 'proud to be a part of Noah's Junior division'. He would go on to lose the belt to Atsushi Kotoge on March 14 at ''Great Voyage 2021 in Fukuoka'', ending the run at just over a month and without a successful defence. On May 2, Yoshioka attacked tag partner Yo-Hey, betraying ''Full Throttle'' and joined ''Stinger'' with Yoshinari Ogawa & Wrestle Gate alumni Hayata & Yuya Susumu. Other ''Full Throttle'' member, Hajime Ohara, joined Daisuke Harada, Atsushi Kotoge & Junta Miyawaki's team. The two stables had an 8-man tag team match the next day, where ''Stinger'' won after Susumu pinned Miyawaki. Yo-Hey joined Nosawa Rongai's new unit, ''Los Perros del Mal de Japon'', and Yoshioka met him at ''Muta the World'' on June 27, where Yoshioka teamed with ''Stinger'' mates Ogawa & Susumu to take on Los Perros del Mal de Japón's Yo-Hey, Nosawa & Dragon Gate's Eita. Yo-Hey pinned Yoshioka after 18 minutes with the '' Yo-Roll''.

In ''Stinger'''s match against Noah Regular Army, Yoshioka scored a submission elimination over former tag team partner Hajime Ohara. He made it to the last two, before being eliminated by Daisuke Harada, and thus ''Stinger'' was eliminated from the tournament.
