Ok say looking through her profile, she doesn’t seem to have any haxes in particular that put Taiyo down, so her main wincon in this match is always going to be just trying to beat Taiyo down. Thus it’s more about how lucky she is to succeed in doing that, so I’ll go over Taiyo’s options.
Taiyo can essentially instantly win if he tags Chisato with either an electric shot from Yae or using the stun gun equipped on the butt of the gun. However Yae’s range atp is limited, idk how in character it is for Chisato to try back up and zone (given Frangible firearms have bad range), but I can presume this will look more like a fire fight where they’re using a lot of cover rather than being close range all the time.
If he can get within a couple meters of her,
Yae does have a limited homing effect and can chain off other conductive materials given the nature of The Path of Least Resistance. So it’s possible Chisato inevitably gets tagged.
In raw stamina Taiyo has her beat ig if it ever comes to that.
If Taiyo does find it hard to get close to Chisato, he could always go the option of
relying on his stealth skills atp, she doesn’t have any detection capabilities and thus can probably be trounced by a sneak attack from him, which he’d only have to employ some of his martial arts moves to grab her with his class 5 and KO her. Being in Tokyo makes this a pretty good strategy cause of all the people, buildings and cover. He doesn’t even make sounds with his footsteps while sneaking for what that’s worth.
Now if the fight manages to stay relatively close range of 5-20m and they find a relatively open area.
Then it comes a bit more on their individual skill. Taiyo at this point can predict people a blitz faster than him and predicted a spy like Kurogao just cause he knew how much of his bag Kurogao knew and didn’t know.
Taiyo’s also got instinctive action if any of her shots catch him off guard and if he really does need to close the distance he can use stepping on flowers to catch her off guard. His Extrasensory will always let him know her rough location if she’s shooting from cover too
I will say (time to slap on the basic science cap) Yae is high voltage up to 8 million V,
and it can heat up or break up non conductive substances. Frangible bullets are meant to break on impact (weak bonds) and aren’t fully solid metal but are also composed of powders (solid metal wouldn’t have a problem with electricity based heating) So Taiyo could clock that he can parry her bullets with electrical shots of his own, weakening them before they actually tag him. Well that and Taiyo’s clothes are bullet proof against lethal weaponry while Chisato’s using non lethal stuff, so combined with his stamina Taiyo can prob afford to make a lot of mistakes
For Chisato idk I’d need someone who knows Lycoris to elaborate on her end (lucky for her Taiyo don’t got Fake Skin, Gun Jamming Gum or Steel spider optional equipment)
