Fairly fast and has decent range. Her staple move for comboing into Horizontal Chemical Love (CL) when 5H isn't possible. Necessary for many combos and gatlings to most normals. Good mixup tool as the jump cancel lets you go into Dive or j.D FDC for overhead options, or you can manual jump install and gatling to 2S/2D for low options. 5K CL 6FRC6 is the standard punish after an opponent bursts badly. The long active frames will catch them falling so you don't drop your burst punish, but you can also use them to catch backdashes.
I-No extends her hurtbox forward on startup, the hitbox shrinks inside the hurtbox for the last 4 active frames, and her hurtbox remains extended during recovery. If your opponent doesn't respect you and mindlessly pushes the wrong buttons in neutral, you can control space with the active frames and let them stick their startup hurt boxes into this attack, but if your opponent knows the matchup, or is mindlessly pressing the right buttons, you'll get blown up. I-No lifts her leg off the ground which could potentially dodge lows at the right range, but her leg can easily whiff over the opponent since the hitbox is so high. You can usually link CL for a 6FRC6 conversion, but some characters recoil in a way that prevents this setup at max 5K range, and this wont work vs crouching either. If they're close enough you can manually JI and use 2D to float them into the CL to get your conversion.
I-No's standing hurt box normally extends up through her hat. This move is a deceptively good anti-air since she leans her head downward; her whole leg starting from where her mini-skirt ends is a disjointed hitbox for the first 3 active frames, with the hurtbox underneath it. The remaining active frames are inside the hurtbox, which expands upward for the trailing 4 active frames, so you need to be on point about timing this to AA with it. On air-CH up close you can confirm into TK Pdive, and if they're far away you can confirm with IAD j.H, with both setups leading to beefy meterless damage. This move might not lead to much on the ground most of the time, but when used properly as an AA you get a colossal reward.
