New developments in the One Punch Man manga are hinting at a romantic progression, although it's highly unlikely to ever occur.
The manga adaptation of One Punch Man by renowned artist Yusuke Murata is capturing special attention from fans. In the latest chapter released on March 23rd, readers have discovered 'some signs that the work wants to start shifting towards a romantic comedy with multiple female leads'.
To determine whether Saitama is suitable for his sister Fubuki, Tatsumaki engaged in a fierce battle with him, which concluded in the most recent chapter. The battle ended with Saitama's victory, but what caught readers' attention were Tatsumaki's contrasting reactions. After the battle with the bald man, the stormy elder sister blushed, a detail not present in the original work.

With details like these added, many readers speculate that Yusuke Murata's manga adaptation of One Punch Man is entering a 'fantasy development' phase.
Tatsumaki once decided to live independently of anyone, while greatly admiring Blast - the ultimate hero. However, Saitama's image now appears in her memories. And that's when Saitama realizes that Tatsumaki's power is quite impressive, with Tatsumaki's cheeks blushing and she shows a happy reaction.

Even she displays the demeanor of a teenage girl when Saitama pets her head. Although Tatsumaki usually shows a disdainful attitude towards others, now she exhibits something akin to a tsundere, especially when facing Saitama.
And fans have reacted to this interesting development with comments such as:
- Tsundere Tatsumaki, who seems to have developed a certain charm for Saitama, looks adorable to me.
- Her face is extremely cute when being petted by Saitama.
- Tatsumaki-chan has fallen for Saitama, or at least acknowledges his existence, something she has never done with anyone else.
However, some others have voiced opposition to this portrayal by Murata:
- It's strange to see romantic developments involving Saitama.
- I think what ONE and Yusuke Murata want to portray in One Punch Man is becoming increasingly different.

Indeed, recent developments in 'One Punch Man' have diverged from the original work by author ONE. Although both versions feature a fight between Saitama and Tatsumaki, the manga's execution is slightly different. Specifically, in chapter 223 released not long ago, there seems to be an indication of a love triangle involving Fubuki, similar to situations in 'To LOVE-Ru', a detail that did not exist in the web comic version.
According to many, One Punch Man has an extremely powerful main character, and stories like these often come with a harem of beautiful girls falling for the main character. Therefore, fans are increasingly skeptical that Murata actually intends to add romantic comedy elements to One Punch Man.
