Global Awakening: I Can Add Points Without Limit

I've only read a few chapters, and the younger sister character, even though she hasn't appeared yet, is really not well-developed at all. Monsters keep invading the city; aren't they afraid the protagonist will die on one of their outings? The younger sister can easily earn hundreds of thousands by killing a single monster, yet the protagonist is willing to work part-time during his spare time for only a few thousand a month?

After reading nine chapters, the sibling relationship is seriously flawed. Orphans, relying on each other for survival, should be either completely distant or extremely close. Given the value of their demonic beasts, even a small amount from the sister would be enough for the brother; he wouldn't need to work and could use the money for more education and training…

I lost interest as soon as I saw the protagonist and his sister tied for first place in some exam; it's utterly ridiculous! The protagonist has a cheat code, but what does his sister have??? This forced first place ranking is so awkward it makes me want to pick my toes, it's like a joke!

I'm outta here. I don't care about single female lead or harem, but I don't like writing about a bunch of women having ambiguous relationships and then telling me it's a single female lead.

It's awkward to watch; he keeps talking about protecting her, it's so pretentious and disgusting.

What exactly is wrong with the current starting point?

I couldn't continue reading after chapter 45. It was utterly unappealing; I only read it reluctantly before it was released for sale.

It's still too childish to read at all.

The author's handling of the younger sister character was poor, which became a major flaw.

What I hate most is when a show pretends to be a harem but then claims to have only one female lead.
