Who is the Strongest Characters of Touhou? (in your opinion)

Seija: Class A-/A
I like you but others are stronger. Seija, why? Why are you so low on the list? You too, Ichirin.

You say that Seija can disable and reflect others' attacks right? ISC Seija is stronger than her DDC self.

This may not be true, but it's possible. Actually, someone beat ISC without using items.

I still didn't pass Seija's SPELLCARDS. I like to grind bullets and get to the border, shot by fairies and that yin-yang looking thing.
For Ichirin, I haven't tried UFO but for ULiL, I smash 'em all, Unzan is the greatest.

Well, I lost my HP because of those fairies and orbs.
After I hold my Shift, Benben, Kagerou and Seija are afraid of me...

Hurt by Unzan? Maybe a cloud could have that much pressure.

I like to grind bullets a lot and at some point I hit those lasers and orbs.
So, I must keep my HP for Seija, her last spellcard is hell.

Cirno: What is a cloud?
Ichirin: I don't want to hurt you but...

Edit: I defeated Seija and get to Shinmyoumaru, She messed with my hit box and for Okina, her last spell is TRUE HELL.

As a beginner, I was confused at Seija's last spell, I did beat her but SHINMYOUMARU IS MESSING WITH MY HITBOX.
Okina? I almost got it, she hit me at that last seconds.

For Junko, I'm stuck at Stage 4 so I haven't played it, thanks for the warning.

Ichirin: They're dumber but more popular than me? Murasa help me.
Murasa: Ok, I'll drag you down to the poll so we could fall together.
Ichirin: No. Then I'll get Nue.
Nue: I'm Falling and my UFO is not working.
Byakuren: We UFO cast will fall... Together we fall...

Me: I'll vote for you, but you guys are lower than Seija. Except you, Nue because I ship you with Seija.
Nue: Seija is my... Slapped by Seija
Seija: Shut up!

Edit: too many typos

It happens to me once, I made a big mistake, hitting at SEKIBANKI'S TRAILS.

Ichirin: A FRIGGIN' UMBRELLA? Really? I'm playable in spin-offs!
Kogasa: It's fun.

Like what I say before, Kogasa is more vibrant than others in UFO cast, I mean more colorful.

Yes, if I die in stage 1 or 2, I restart the gameplay, but it's no longer my problem in DDC. GODDAMMIT SHINMYOUMARU.

I don't think Kogasa looks like Yuuka, but the comic "Do Your Best Kogasa" probably make her popular.
Raiko is more similar to Yuuka than Kogasa, she looks mature enough.

Touhou restart limit.
TD: Stage 1 2 3 and before boss
DDC: Stage 1 2 3 and before boss
LoLK: Stage 1 and the others, ignore them, they want my HP.
HSiFS: Stage 1 2 3 4 and before boss

Kogasa x Koishi, I've heard that before...

Ok... Gotta go fighting with Shinmyoumaru.

Finished with Miko Fight cause she couldn't help me with my grind.
People think I'm new here because I keep losing all the time.
All day long I beat Benben but nothing seems to sastify.
Gonna lose my mind if I don't beat Futo to pacify.
Can you help me? Occupy Seija? Oh yeah!!! (Parody of Black Sabbath's "Paranoid")

I just love Black Sabbath... I just talk about my feeling.
Edit: In your country, France, there's a metal band called Alcest, you may try to listen to their songs.
