The World

Welcome to Ran University

Beneath a sky laced with circuitry lies a city where knowledge is power - literally. Three rival academies train students in the arts of combat, and every lesson ends on the battlefield.

As a new enrollee, you will choose your school, master a fighting discipline, and forge alliances with fellow students. Rise through the ranks, lead your club to victory, and claim the campus for your school.

The Three Schools

Every student belongs to a school. Your school is your family, your army and your pride.

“Steadfast as the Gate.”

Guardians of tradition and discipline. Sacred Gate students hold the line with unbreakable resolve and fight as one impenetrable wall.

Mystic Peak crest

“Wisdom from the Summit.”

Seekers of hidden knowledge atop the emerald mountain. Mystic Peak masters strategy and arcane insight to outthink every rival.

Phoenix crest

“From Ashes, Ascend.”

Fierce and relentless, Phoenix students burn with ambition. Defeat only fuels their fire - they always rise again, stronger than before.

Installation Help
"Unable to execute file … CreateProcess failed; code 740. The requested operation requires elevation."
Click OK. The installation finished; only the automatic start was blocked because the game launcher needs administrator rights. Open RAN Online Catalyst from the desktop or Start menu shortcut and click Yes on the Windows prompt.
"Windows protected your PC"
Click More info, then Run anyway. Windows shows this for new games it hasn't seen often yet.
The launcher asks for permission every time
That is normal: it needs administrator rights to download updates into the game folder. Click Yes.
The installer is deleted or blocked right after downloading
Windows Defender (or your antivirus) sometimes removes new installers before you can even run them, since they're not widely downloaded yet. Open Windows Security → Virus & threat protection → Protection history, find RAN Online Catalyst in the list and choose Restore/Allow on device, then add an exclusion (see below) before installing again.
The game gets closed, quarantined, or flagged while you're playing (not just during install)
RAN Online Catalyst includes built-in anti-cheat protection: while you play, it checks other programs running on your PC against a list of known cheat tools. That kind of check - looking at what else is running - is also the kind of behavior some antivirus engines watch for, so Windows Defender or another AV can occasionally mistake it for a threat and quarantine or close the game. This is a false positive, not a real virus. Fix: open Windows Security → Virus & threat protection → Protection history, restore anything it removed from the game's folder, then go to Virus & threat protection settings → Manage settings → Add or remove exclusions, and add an exclusion for the folder you installed the game into. Only ever download the installer from this official page - that's the one way to be sure you're running the real client and not a tampered copy.
