In Kuuga's World: As Flame Dragon Man, I Burn Away All Evil

[No heroine + no or minimal OOC + not saintly + relatively lighthearted plot + slow pace]

[Main world: Kuuga, Agito + side quests: Decade, OOO, W, Den-O + to be decided]

Synopsis 1:

Li Yu transmigrates to 2000s Japan with a Huo Ying Stone pendant that lets him transform into Flame Hero, and gets caught up in the story of Kamen Rider Kuuga.

After meeting police officer Kaoru Ichijo, Li Yu becomes a senior and comrade-in-arms to Yusuke Godai.

Godai: What do I do if I can't beat the Gurongi?

Li Yu smiles: No worries. Just take a lot more beatings.

Godai: What do I do if I want to get stronger?

Li Yu smiles: No worries. I'll just give you a shock. I guarantee you'll go from a weakling to someone who's strong and only strong.

Godai: What do I do if I'm afraid of Daguba?

Li Yu smiles: No worries. Leave him to me. Flame Armor! Combine!

Passing by, Wang Xiaoming sees Li Yu and glares with hatred: Flame Demon, you drove a wedge between me and Natsumikan and bullied my little sister. I'm not done with you!

Passing by, Kaito Daiki sees Li Yu and can't help but feel afraid: Flame Demon, I'm sorry! Give me my underwear back! I won't steal your stuff again, okay?

Passing by, Kaoru Ichijo gives him a thumbs-up!
