Tsunayoshi Sawada’s Forum Quest to Save the World [Crossover]

Sixteen-year-old Sawada Tsunayoshi accidentally stumbled into a bizarre forum dripping with chuunibyou vibes. Just looking to lurk and see what was going on, he clicked on a few of the latest posts.

Before reading, Tsunayoshi was calm.

After reading, he dropped his popcorn all over the floor.

"Saving the world in style". That was the name of the forum, right?

Could someone explain what the user "Strawberry Sundae" meant by tennis that kills people?

And what's with "Explosion Maniac" threatening to blow up the moderators every other minute?

Weren't you supposed to be saving the world?

What are you guys even doing...

I'm calling the police. I really am!

Reborn, kicking him from out of nowhere: Don't do anything rash, stupid Tsuna. This forum is about to become your training ground, too.

Sawada Tsunayoshi, completely baffled: What?

Reborn, looking perfectly at ease: Starting today, you and the others are members of the forum, too. Do your best to complete the missions.

Please note:

1. One-on-one romance. The male lead is our angel Tsuna, and the pairing is clear, though there will be some one-sided crushes along the way.

2. Lots of side pairings, including SasuNaru, TodoDeku, and Yamamoto-Gokudera. Some feelings may be one-sided, but the endings are still one-on-one. The unrequited crushes will generally end up helping the couples.

3. The plot has little to do with the original stories.

4. There are lots of characters, including original ones, and they may be OOC. Please be gentle.

5. The worlds, in order, are My Hero Academia, Naruto, The Disastrous Life of Saiki K., and Vongola.

6. Slow-paced, with slow transmigration.

7. Updates are usually between 11 p.m. and midnight.

My next upcoming story is: "Every Day Tsuna-Nyan Heals and Protects the Guardians"

Here's the blurb:

The Vongola family faces an unprecedented crisis. For some unknown reason, Vongola Tenth Sawada Tsunayoshi falls into a coma and doesn't wake up for ten days. The Guardians are in chaos.

On the same day Sawada Tsunayoshi falls into a coma, a new character, Tsuna-Nyan, appears in the popular Japanese fan manga "Rainbow Story".

Tsuna-Nyan is shocked to discover that he's ended up in a fantasy world filled with monsters and ghosts, and that he isn't even human himself.

In this world, Tsuna meets Hayato Gokudera as a jaded fox spirit, Takeshi Yamamoto as a Taoist master, Mukuro Rokudo as a lotus immortal, Hibari as a demon king, and Reborn as a heavenly master and demon hunter.

Though they look like his own Guardians and have similar personalities, they are, in the end, not the Guardians themselves...

Tsuna-Nyan never stops looking for a way to get home.

The fox spirit and the others spend every day trying to coax the little cat into playing with them. At last, they realize why Tsuna-Nyan is so distracted, and they become twisted...

What, you see us as substitutes for someone else?!

The BOSS is as beloved by the Guardians as ever, but in the end, the Guardians start fighting among themselves.

No CP, just friendship, though there will be a love polygon involving the Guardians.
