Rosanna is a Burst I Machine Gun wielder who specializes in Stealth and Assassination. Sadly, only on paper, because in reality, it's super hard to make use of her in PVP, and in PVE, the kit doesn't do anything at all.

Rosanna's Skill 1 is one of the skills that sounds great on paper but is terrible when you test it out in the game. After landing 120 hits, Rosanna uses a Stealth mechanic to hide herself from enemy attacks - so she can't be targeted by any single-target skills, but sadly AoE skills and even basic attacks that have splash ignore the mechanic and will cause her to get hit. Rocket Launchers are the biggest reason why it's super hard to make use of it in PVP - in most cases, she will instantly lose the Stealth right after obtaining it.

The second part of the skill will Dispel 5 buffs from the two highest ATK targets nearly at the start of the battle. This will remove for example Jackal's damage share, so in certain situations, Rosanna can act like a counter to the arena nightmare Jackal is, but similar to the first part of the skill - it looks only great on paper because it comes at a heavy cost to your own team. Mainly that the rest of Rosanna kit's does nothing, that she's an MG wielder and has a 40s cooldown on her Burst. Also, Overload gear buffs aren't affected by the Dispel. As for PVE, the skill basically does nothing too.

Rosanna's Skill 2 again gives her the Stealth mechanic, but this time it triggers it right at the start of the battle. This will also be stripped nearly instantly in PVP due to all the Rocket Launcher teams. The second part of the skill gives Rosanna a massive ATK buff whenever a NIKKE dies - so this includes those on her and the enemy team, which means that if you keep her alive long enough, her ATK will skyrocket. The issue is that this rarely happens in reality.

We also tried to abuse the Burst Gauge fill bonus by putting a sacrificial lamb on our team (either a level 1 character or a stripped one) to get an advantage over the enemy team and Burst before them, but again - the on paper vs reality conflict took us by surprise. Not only the CP penalty is super harsh, but also the Burst Gauge you get when the sacrificial lamb dies isn't enough to make it worth doing - you would get a similar amount if the character would stay alive and just keep shooting at the enemy. So again, another nearly useless skill even in PVP - in PVE you can ignore it fully.

Rosanna Burst has some great multipliers - good enough to assassinate 2 targets at once - but triggering the second part of the skill is really hard in PVP and you need to build the team around Rosanna to make use of it. Otherwise, she simply has too many issues staying in the Stealth mode to realistically make use of it.

Rosanna is a purely PVP character that sadly doesn't even work there either due to how the current PVP meta looks like - Rocket Launchers simply make her Stealth mechanic obsolete. Also, since she's an MG wielder, her own burst generation is terrible, so even if she managed to remove some crucial buffs on the enemy side (like Jackal ones), you will still lose the battle in a lot of cases. Overall, she can work well at lower ratings and against not fully optimized teams, but against the current Meta she is useless. The fact that she is Burst I with a 40-second Burst cooldown doesn't help her either.

Also, she's totally useless in PVE. Like really useless.
