(Champion Suggestion) Saruji, Demon of the South Wind
Possible Jungler / Toplaner
Saruji would be based off Oni, a mythological creature of Japanese origins. Personally, I'd love to see more Asian themed champions coming from Ionia and I think this could be a good one - whether it's just a few ideas that get worked into something down the road or just the entire idea ported in.
Saruji would have two forms, somewhat like Nidalee. His first would be similar to Jhin's in the fact that'd have his attack speed locked (or at least reduced) because he'd use a large two handed sword. This would be a somewhat tanky version I suppose. His next form would take his sword and split it in two - increasing his attack speed but reducing his overall damage to possibly something like 90% (or basic attacks only deal 90% of base damage)? (Maybe apply magical damage on hit? I'd really like to see him with rageblade). You could use this for an R, like Nidalee's but possibly with a longer CD. (Possibly give it a cast time?) P
In the first form (big sword) he would swing his blade forward in a cone like shape, any targets hit would be pushed away. In second form (two little swords) he would leap on his target. Q
First form could have like a shield that outright blocks all incoming damage for half a second? Maybe a second. Or just be a shield that taunts nearby enemies while he laughs. Second form could just be an attack speed steroid - increasing his attack speed for a certain duration but reducing it afterwards until it's off CD (like Master Yi's Wuju Style but with attack speed instead of AD kinda). W
First form would have a charge ability (similar to Gragas or Sejuani - not much else to say). Second form would have a whirlwind spin attack that would launch him forward while he spinned in the air, applying basic attacks and on hit effects for a few strikes. E
Name and title are kinda placeholder, could be easily changed.

It's a rough concept and could definitely use some work, feel free to suggest any changes.
