Hey! I'm looking for manga suggestions for stories about main characters who work hard and care about improving the world around them while also following their own dreams. They can be in any genre. 4w3230

These are the only examples I've found so far:

(but I'm open to suggestions that are very different than these too)

• Akuyaku Reijou wa Yoru Tsugedori o Mezasu
• Ascendance of a Bookworm
• Isekai no Sata wa Shachiku Shidai

What I'm Not looking for:

• No ecchi or fanservice.
• Video game style power ups that are purchasable or otherwise happen without the MC having to use their own existing ingenuity or knowledge to improve things incrementally

thanks!
