Basically the title, Yoru's flashes are underrated in terms of the duration it flashes you. It's really perfect timed and I feel like all flashes should have this duration of flash. You get blinded by breach or sky and you open your eyes directly in the next round whereas Yoru's flashes let you actually be able to dodge it properly and even when you can't, it doesn't last for for 2 years straight. The color of Yoru's flash is also really forgiving to my eyes lol
