A Whole Lot of Clicking
Bleach Online is a role-playing game: which means you create your own custom character in the Bleach world, choose their gender and class, and level and power them up. Characters learn new moves, gain new items, and capture souls in the human realm.
Along the way, you find different companions to fight alongside you from the Bleach universe. Main characters such as Ichigo and Rukia help you along the way, and if you have a favourite character in the Bleach world- its probably in the game.
The loading screen has some "interesting" views of some female Bleach characters. To be fair, the Bleach anime and manga are kind of made purposefully for teen guys and there's a lot of fanservice in them.
If you want to ignore this aspect or like this aspect of the game, then you'll be fine. I wouldn't really recommend this game for anyone younger than 16 though (just as I wouldn't recommend Bleach to anyone younger than 16). Either way, that stuff isn't the main quest for the most part. You can kick Hollow and Quincy butt without it.
Its fun and easy to level up, and watching the in fight animations is pretty entertaining. Characters can surprise you with different techniques in battle.
One tip- make sure to format your troops and consistently upgrade and add items to each of them. This is the most efficient way to ensure victory and max out on your overall team strength.
Fighting against the AI in the game doesn't tend to be difficult, but it is important to take care of your strength when it comes to competing against other players.
