Kenichi (the protagonist) has no talent in martial arts. He starts off as weak and bullied, but with time gains the power to protect himself and his adversaries.
There are several training arcs in this one, with plenty of battling. The techniques imparted to the protagonist have thought put behind them and play a role in future fights. Battles tend not to be one sided either, particularly toward the beginning of the series.

The MC in this one experiences psychological growth over his involvement in several death games. He earns the respect of his peers over the course of the narrative, but is no stranger to faltering.
The series' focus on psychology can drag on. If you're more into the death game aspect over the psychology, then you might find yourself put off by this manga - particularly in its latter stages.

This one is a slow burn. You have to make your way through the slow beginning to get to the meat of the story and what the central conflict is. Several arcs work to build the lead and his group up in strength.
Our lead in the story is weak and scared but has conviction when the people he cares about are in danger.

Features a death game where participants become God if they win. Gasai Yuno, the quintessential Yandere, plays a significant role assisting Yukiteru (the lead). Yukiteru is really weak at the start of the story, but with time pushes through those hang ups. His growth is not physical, but mental - though some found it a cringey and poorly paced.

The protagonist does have an advantage early on, but with time has to train and grow to move forward. This series is primarily based around a tournament arc.
This series dragged on for me personally, so keep that in mind if you decide to give it a read.

This is a romance story that centers around a rather peculiar curse that the lead, Tousuke Rokudou, has. He starts off as weak and nerdy, but with time takes steps to strengthen himself through martial arts. He learns to lean into his problems, rather than to run away from them.
I personally found the romance in this one underwhelming.

A typical example of the zero to hero formula, though the strength the protagonist Jin-Woo gains isn't exactly earned, but granted by something larger and more powerful than himself.
