It is possible to reroll in CZN. However, each reroll attempt takes a long time, so it is generally not recommended.
You Can Get a 5-Star Character After About an Hour of Play

CZN has a beginner-exclusive gacha that guarantees a 5-star character within 50 pulls. Since you can get a 5-star character with about an hour of play, you can decide whether to continue after seeing those results.

In CZN, you can pull from the gacha 200 times just by playing the early game. There is also a pity system that guarantees a 5-star character, so it's recommended to just start playing without worrying too much about your initial gacha results.
Training Is More Important Than Character Performance
In CZN, a character's strength can vary greatly depending on the Save Data created with Chaos Manifestation. Even low-rarity characters can perform very well depending on their Save Data, so there's no need to force yourself to aim for high-rarity characters.

Which Gacha Is Recommended?
The Pickup Gacha is Recommended

The Pickup Gacha has increased drop rates for featured characters, making it easier to get the characters you want. It is generally recommended to reroll on the Pickup Gacha.
Pickup Characters Are Not Limited-Time
InCZN, all non-limited characters, excluding collaboration or seasonal characters. will be added to the Standard Gacha after their pickup period ends. This means it's not absolutely necessary to pull for them during their banner, so rerolling on the Standard Gacha is also an option.
When to Stop Rerolling
Stop Immediately if You Pull an SS-Rank Character

When rerolling, we recommend starting the game as soon as you get one SS-Rank character. In CZN, teams consist of only 3 characters, so having just one powerful unit is enough to progress smoothly through the early game.
