Tengen Uzui's flashy personality and incredible swordsmanship has won over the hearts of thousands of anime fans. Since becoming a key member of the Demon Slayer cast in the most recent Entertainment District Arc, Tengen has proved that he is an invaluable member of the Demon Slayer Corps.

Tengen has also proven that he likes to keep a combination of beautiful and powerful allies around him at all times. In just the short amount of time he has spent in Demon Slayer, Tengen has shown an ability to win over the hearts of women, children, and even a pair of unnaturally muscular mice.

10 The God Of Festivals Would Fit In Great Next To Satoru Gojo

In a world as grim as the one found in the Jujutsu Kaisen anime, Satoru Gojo sticks out like a sore thumb. Despite regularly coming face-to-face with the darkest parts of the human spirit, Satoru rarely loses his bombastic personality.

The ability to maintain a smile through turmoil is something that Demon Slayer's Tengen Uzui respects more than anything else. Of course, if Tengen and Satoru's personalities ever clashed, Uzui could settle with the fact that Gojo's overpowered cursed technique makes him an indispensable ally.

9 Tengen Could Teach Hisoka The Difference Between Gaiety & Creepy

The clown who haunts the world of Hunter X Hunter could hardly be considered a hero. His hedonistic behavior while in the presence of Gon and Killua is enough to condemn him, but fans continue to show Hisoka love because of his exuberant personality.

After bonding over their affinity for flagrancy, Tengen and Hisoka would quickly bond over their lost limbs and then spend the rest of their lives sharing makeup tips. Fans can easily picture the morning training routines that follow their flashy sleepovers having Hisoka creepily licking his lips while Tengen geeks over the versatility of bungee gum.

8 All Might's Strength & Bold Personality Would Attract The Beautiful Smile Of Tengen Uzui

The beacon of hope for thousands of aspiring young heroes may not be the man he used to be, but My Hero Academia's All Might has not lost his way. Though much of his strength has been sapped out of his once indestructible body, the personality behind All Might still exists in the frail body of Toshinori Yagi. This personality is bold enough to shout every time he enters the room, which is something Demon Slayer's Tengen Uzui would appreciate while working alongside Japan's greatest hero.

7 Miss Blizzard Would Fit In Perfectly Alongside Tengen's Three Wives

Surely nothing would catch the attention of the flashiest pillar of the Demon Slayer Corps like the leader of the Blizzard Group. After seeing the small harem of B-Class superheroes that Fubuki has put together, Tengen would have no trouble joining hands with Fubuki, the powerful esper from One-Punch Man.

Furthermore, Tengen's confident persona is something that Fubuki could learn a lot from. As long as the two avoided contact with the Demon Cyborg, Genos, Tengen would fit right into the satirical world of One-Punch Man.

6 Naruto's Shinobi Training Goes Even Further Than Tengen's

Dropping Tengen Uzui into the world of Naruto would break the power scale created within the Demon Slayer mythos. Demon Slayer has managed to compete with classics like Naruto by creating a simple power system that offers the average character enhanced abilities through breathing techniques.

Tengen further enhances his skills by pulling from an arsenal of tricks that he learned while training to become a shinobi. If Tengen's eyes ever opened to the ideas of chakra, ninjutsu, genjutsu, and taijutsu he would quickly surpass the strongest members of the Demon Slayer Corps.

5 A Scarred Past & A Flashy Personality Are Just Two Things Black Star & Tengen Have In Common

Black Star _ Soul Eater

Alongside Tengen Uzui, Soul Eater's Black Star is one of the flashiest characters in the anime genre. As the last surviving member of the infamous Star Clan, Black Star moves through the world of Soul Eater with a chip on his shoulder.

This chip is something that Black Star and Tengen have in common. Before joining the Demon Slayer Corps Tengen abandoned his father and brother, leaving his shinobi clan behind to find his own way. This commonality would make Tengen a great ally and mentor for Black Star.

4 Usopp's Versatile Skill Set Makes Him An Invaluable Ally

One Piece's Usopp is one of the most versatile characters of the Straw Hats crew. Though often recognized for his marksmanship, Usopp is also a skilled diplomat, engineer, strategist, and artist.

Demon Slayer's Tengen would have no trouble teaming up with Usopp. While the Sound Hashira uses his swordsmanship to get in close, Usopp could lean into his strengths as a marksman as long as he packs some wisteria-tipped bullets.

3 Filo's Selflessness Would Easily Win Over The Heart Of The Sound Hashira

The Rising of the Shield Hero's Filo has quickly proven that she is one of the best support characters introduced in the new generation of anime. As the primary support to the man many presume to be nothing but a support character, Filo has learned what it means to selflessly offer herself up to her allies. This alone makes Filo a worthy ally to Demon Slayer's Tengen Uzui.

2 The Leader Of The Tokyo Manji Gang Could Teach Tengen A Few Lessons On Leadership

The prolific martial artist and leader of the Tokyo Manji gang would be a valuable asset next Tengen Uzui. Both characters are natural-born leaders who recruit through honest demonstrations of their strengths and weaknesses.

Tengen could even learn something from Tokyo Revengers' Mikey in terms of recruiting. The Sound Hashira's introduction showed that his methods veer a bit too close to kidnapping — something Mikey would never do when recruiting allies. Mikey would surely lend his new ally some advice in exchange for some training in breathing techniques and swordsmanship.

1 Asuka Would Have Volunteered Immediately To Join Tengen On His Adventure Into The Entertainment District

The head strong pilot of Evangelion Unit 2 would be lucky to have Tengen Uzui as an ally and a mentor. Of course, doing the mental work to fit Asuka's Evangelion unit into the world of Demon Slayer makes it hard for fans to imagine these two characters teaming up.

Still, Tengen would respond to Asuka's tenacity with a patience that few of her peers from Neon Genesis Evangelion offered. Asuka would also give Tengen a leg up against the likes of Muzan Kibutsuji in her giant mecha.
